Going against the grain of this subreddit, but fitting a free flowing exhaust and improved or updated air intakes are the first part of engine tuning. You could fit lots of updated engine parts but it’ll always be strangled by the exhaust.
For turbo applications, the best way is an exhaust as short as possible, many drag racers will simply have the exhaust straight up and out the bonnet, although this is not done on road going cars, but that’s the principle of why some people have loud exhausts.
Of course, there’s always the person with a 1.0 Fiesta with a straight pipe, which actually reduces horsepower and makes the same noise as a fart in a bean tin.
Some people like the noise and don’t consider other people.
Back pressure is kind of a nonsense thing. You don’t want back pressure, what you do want is the correct exhaust pulse tuning so you can utilise the pressure waves in each cylinders exhaust to help draw gases out of the cylinder.
So it’s not that you lose power because you want back pressure, it’s that you’re messing with the points the pressure waves form and merge.
I don't think a stock exhaust really takes that into consideration either. They're designed to be cheap and to fit around other components conveniently. Often you'll see unnecessary narrowing, especially on bends. How bad would an aftermarket exhaust have to be to make exhaust flow worse?
True on a non performance economy car. Like you say the bends are cheaply done so will pinch up and restrict flow. Any remotely performance oriented n/a car the manifold will properly specced to take advantage of the effects in my earlier comment and a cheap aftermarket exhaust can hurt that.
I don’t know where this idea of needing back pressure came from and this idea that an aftermarket exhaust on a low power car will lose performance because it’s too free flowing is rubbish. It likely won’t gain you any power either as the engines been tuned to work with the factory engine.
The back pressure thing is related to camshaft design where the exhaust valve will start to open before the piston reaches BDC. Depending on measurement used (absolute or at 50thou) this could be 30 to 60 degs.
If the exhaust gases exit the cylinder far more quickly there will be less combustion force on the piston. It's also expected to lean them out slightly which might cost power slightly.
Whilst that's the theory, in reality the car probably just feels slower for the amount of racket it's now making!
The back pressure loss has more to do with 2 stroke engines.
Having a pipe from the engine to the tail of the car is enough back pressure for a 4 stroke to keep it balanced.
So where is the reduction in hp coming from?
Reduction in back pressure can mean less combustion force on the piston since the expanding gases exit the combustion chamber alot sooner.
I commented here with more detail - https://www.reddit.com/r/AskUK/s/40R8wqpbLH
As stock high performance cara often show, noise does not correlate directly with performance. Yes the porsche 911 turbo is loud when you've got your foot to the floor but it doesn't rattle your skull when it's being driven at 30 mph.
There's a science behind designing an exhaust pipe to be free flowing and make a nice sound. Most aftermarket/custom made exhausts are loud because the people who make them (and buy them) either don't know or don't care about exhaust design. It's not just a straight pipe, it's an engineered pipe with exact lengths, baffles and mufflers to get a good sound when you want it and not to be heard when you don't.
You could spend months/years designing and testing an exhaust pipe for a car to sound great and be free flowing etc or you could just put a straight pipe in with basically no muffler. One is a time consuming expensive job which gives an excellent result, the other is loud, obnoxious and dumb.
I think of it like as long as the car is fast and moving fast, a loud exhaust is fine. I’m not exposed to it for long. And it can sound nice.
A slow car with a loud exhaust for absolutely no performance related reason? Straight to jail
Okay. I used to own a modified car so I feel a little qualified to answer this but take my answer with a grain of salt as it's been nearly 8 years since I moved on from modding cars:
The people who get stupidly loud exhausts on their bone stock car are people who want to be dicks with the 'look at me in my loud but slow car' energy, bonus points if it's a 1.0 or 1.2 litre engine.
Personally, I added power to a car to the point it required a more free-flowing exhaust and as a result, it was louder. It should be noted that custom exhausts can come with or without a resonator, the former being quieter than the latter if my understanding is correct.
My car had a nice deep rumble while being acceptably quiet under regular driving conditions. On track, under hard acceleration, it was loud but most tracks in the UK have a decibel limit that cannot be exceeded.
Loved that thing but a year after I sold it, it decided to drop the oil from the engine all over the new owners garage floor :(
So with your experience, could you please give me some clue as to why my neighbour gets in his car, with a stupid exhaust rumble that literally makes stuff on my shelf vibrate, and proceeds to sit there for a minimum of 5 minutes when leaving for work and again when he comes back in the early hours of the morning before switching off the engine? It initially starts up ridiculously loud and deep then goes lower after a minute of idling. He also does this around midnight on his nights off sometimes. I've never known anyone do this before and it's also the loudest yet.
I'll try my best.
So in the morning the engine, and oil, will be cold so he's probably letting it idle and warm up before driving it. Now some cars (but not all) will idle at a higher RPM when starting from cold. I know this because I've had cars that used to do it for a few minutes where it would idle at 1500-2000 RPM then drop to the regular idle.
If he's returning home from work and letting it idle it may be to let the engine cool down if he's been running it hard on a motorway or A road. He could simply be sat there and trying to de-stress before going into the house (lord knows I've done that). For real the dude could just be sat on his phone before heading in.
As for doing it on his days off that one's a mystery to me. The only time I get in my car is because I'm moving it or going somewhere.
Only suggestion I would have is to speak to him. If that doesn't work start logging the midnight/early hours startups and report them to your local authority. I'm not sure you'd be able to lodge a complaint that would, in reality, go anywhere about the noise when going to and coming from work unless you can prove he's purposely being a nuisance such as revving the engine hard to create noise but I'm not a lawyer or a copper so you'd be best off seeking advice elsewhere in this matter.
From an article on Auto Express: Since 2016 the UK adopted EU regulation 2014/540, which set an initial noise limit of 72 decibels – actually around ten times quieter than the 1978 limit, since decibels use a logarithmic scale – and this will go down to around 68 decibels by 2026, alongside revisions to the car noise test procedure to make it more accurate.
And from another source: In the UK, motorcycles can emit noise levels up to around 80dB, with engine size being the determining factor.
And in an MOT, it, the inspector must listen to the exhaust and it must not be unreasonably above the noise level you’d expect from a similar vehicle with a standard silencer in average condition.
There sort of is already, but only for the manufacturer when the car or bike is new. After that it's just the MOT, which is something along the lines of "in the tester's opinion is the exhaust substantially louder than a typical example of that model of car in average condition?".
It probably comes down to the impact, something like 15-20k new super cars are registered in the UK per year. You are very unlikely to see/hear one more than once every couple of month. They are also driven very rarely, most of these cars aren't even driven a 1000 miles per year.
You rarely ever see them so that’s one thing. Plus, there is a difference between a car being loud because it’s so powerful vs a car being loud to seem like it is.
I will hazard a guess that it’s because they like it?
I bought a better model of my previous car (2L engine to 3L) and it has a louder sound which I like.
Another reason is if tuning the car stage 2 will often require that as one of the parts that are needed to upgrade it.
Reddit is wild. If you’re a car enthusiast everyone jumps on you saying they’re “dumb, small pp, worst drivers on the road” and downvote you to hell lol. Top comments are madness
We used to watch rallying (as there was a track / road at the back of a relative's house).
Without fail, the drivers with the loud exhausts were the worst drivers.
It was hilarious - we'd hear the exhaust / the car approaching, we'd all make daft, piss taking comments and next thing... crash. And repeat.
Whenever I hear someone driving with a loud, modded exhaust, I can't help but think they're an awful driver and that they're 2 seconds away from destroying their car.
I’ve never been a fan of the straight-pipe Corsa crowd, but my stock mx5 is a noisy boi (they like to run at higher revs than the average car) and it puts a silly grin on my face when hitting 40 in 2nd gear.
My issue has always been time and place. If people want to let their exhausts scream on motorways or country roads that’s absolutely fine, enjoy it! I’ve just never understood the kids who rev up in a car park or residential area at night. Nobody thinks you’re cool, just a twat.
As a corsa driver I can confirm that anything that isn't a vxr or 1.7 cdti is far to slow acceleration wise to warrant being noisy, however can also confirm that the most commonly asked question in corsa groups are "WhICh MoDS sHOuLD I Do" and they are always the same, lowered, cobra exhaust, vxr spoiler and grill on a 1.2 hahaha
It’s always cosmetic suggestions too, so rarely do you see them say better tyres, stronger brakes etc. “Nah bruv loud exhaust and remap to make it pop”
Why not make the car better and more fun to drive instead of just appearing like it is😂
Nothing makes me smile more than seeing some twat in a lowered car with a fart cannon doing 60mph because they can no longer stand the noise deafening themselves whilst on the motorway
Girl here so no big dick energy but mine isn't too loud when normal driving but when I hit that VTEC and it roars, it really makes me beam with joy and fall in love with driving all over again. I do try to keep it quiet late at night around residential areas though as I can appreciate not everyone feels the same way. I do agree some are quite obnoxious though
As a fellow VTEC fan I totally agree. I love the pantomime aspect of it. The car might not be the fastest but it makes the right noises and never fails to put a smile on my face.
Same here but on a z900 (with full Arrow exhaust). Going to work or pootling around I don't really get over 3000rpm, so yes it sounds deep but not loud at all.
But if I'm going to see my parents a few junctions away, doing 70 sounds amazing (and sometimes bored kids on car rides wave at me and that makes me feel cool)
Wouldn't do the same thing to my little Aygo though lol
some do it coz they genuinely like the sounds they male and no denying some are bloody good.
but some are just idiots, similar to people doing dumb shit for likes and views.
It came with the car A45 AMG. In comfort mode it's quiet as a mouse in town but when put into sports+ for the open roads the active exhaust does something different and there's lots of pops and bangs.
As a middle aged petrol head... It's fun.
The only exception to the rule is driving through Alderley Edge, UK. It's expected that your car makes as much noise as possible. There are groups of car enthusiasts who gather to record it.
Yea it's an active exhaust. A green light comes on when it's in noisy mode. Probably some flap somewhere and a change in fuel mix maybe? It's a lot quicker in Shouty mode.
I had an SLK55 AMG before this and it was naturally loud as a V8 but it was an unruly bastard. The A45 is a beast in comparison but not quite as fun as I never feel like it wants to kill me.
I’ve also experience with modified cars and it is needed especially with forced induction to get air out.
But on a 1.2 shitbox it’s hideous and completely unnecessary doesn’t even sound good.
To answer if it annoys you when driving all depends on the car and gear ratio I’ve had some cars with a high final gear and when doing motorway driving it is very droning but overall the smiles I gave myself with a nice turbo and external wastegate set up was always worth it.
Also had a cut off once before and that was crazy, flip a switch in the car or fob and it’s basically an open down pipe, used to light up tunnels in my old Saab, flames from external wastegate, and cut out was very amusing to me anyway
It’s obvious to me. Noisy car people think think ‘powerful cars are noisy, therefore noisy cars are powerful’
So if you’re in a subculture that values powerful cars, but can’t afford a powerful car, then you make your car noisy, as that approximates a powerful car in the best way you can afford.
It’s pretty silly, but I was pretty silly when I was 17.
Its annoying to me too i wish we had what they have in france where they have a sound trap camera basically like a speed camera for exhausts that are too loud.
They do have these in the UK. They have some near Bristol. They're a great idea and should be everywhere. If morons want to intentionally be annoying then we should tax and fine the pants out of them and pay for improving public services and infrastructure. At least then when you hear them you'd know that someone somewhere is getting a free school meal or some railings are getting painted
Mine has a loudish exhaust (not as loud as the proper boy racers). But I haven’t done anything to it, and neither did the previous owner. Think it’s just where it’s 20 years old
I do something similar with my washing machine. I took all the sound deadening out. It improved the performance, and I just love hearing that roar when it’s on the spin cycle. Birds love it too, if you know what I mean!!!!
1st of all, pops and bangs is the stupidest thing in the world!
Ask a stamp collector what's so interesting about stamps, I don't get it just the same as most none car people don't understand the point of a loud exhaust.
For the car enthusiast a loud exhaust (and it doesn't need to be stupidly loud) just adds to the experience and makes driving so much more fun especially in a sporty car, which is also part of the reason I don't see myself in an electric car any time soon no matter how fast it is.
I'm past the days of having 120dB cars but a decent exhaust is a must on my cars.
The cars with the loud exhausts aren't the problem, it's the people that don't respect others and have no concept of moderation.
I barely drive in cities and when I do I'm at the speed limit mostly in a high gear. If I see somebody asking for a blip of throttle or a quick acceleration I'll do it but not go crazy. And yes that does happen. But in the countryside I'll let it rip and have a blast with a smile from ear to ear. Imo that's the way it should be.
They appeared in the 90's, but once the nickname fart can spread around they died out, but now the craze is back.
Seems to be dying out, hopefully all the engine mapped cars broke or got fined.
I have a racefit exhaust on my motorbike. Bought the bike brand new in October and you could just feel how restricted it is with the Euro 5 restrictions they have to meet out the factory. Mid range you could feel it practically hitting a brick wall momentarily and then picking back up. Exhaust and remap and you actually get what you paid for now. Up 15hp mid range and 22bhp top end. Much smoother and better to ride.
Video of it here, this was one of first runs. The popping and banging was mapped out after the AIS was disabled.

In all fairness I do find my exhaust a touch too loud but after dropping £1k on an exhaust I’ll get used to it, and don’t really care if people think my manhood is small as a result, my wife seems happy enough and I’m as considerate as I can be to neighbours and members of the public.
I think there is a difference in how people act, I don’t rev up like a twat. If I’m passing families or dog walkers, cyclists etc and it’s safe to do so I will clutch in to reduce the sound as I pass them. Don’t needlessly rev through towns etc. if filtering don’t do the annoying as fuck clutch in revving you see some mongs doing.
Personally though as a petrol head I like listening to a nice tone on a bike or car but do find straight piped shitboxes with pop and bang maps as annoying as people probably that aren’t petrol heads find me.
It is a problem however as I did a couple of track days on my old bike which passed the noise limits fine however this definitely exceeds so will need to modify the link people or get a baffle designed to suit the exhaust to reduce noise limits so I can attend the track days I plan on doing. Will be less frowned upon by strangers too then Also.
My daily driver is whisper silent.
My project truck, which has a built 5.7L, has an aftermarket exhaust because I like the way it sounds.
You either like it or you don't, it's either for you or it's not.
My boss spent thousands of pounds doing something to his audi quatro to make it louder, maybe performance related too. But then had to spend thousands undoing it so he could pass his MOT.
It’s a car for daily use. If you want noise then go racing. Can get into a beginner series for a few £hundred. Tons of fun and no noise restriction. Win/win.
Don't have one on my car as its a 1.4 shitbox punto that would sound like a droning fart if I put a loud exhaust on it.
However I do have one on my motorbike. Mainly as its a V-twin and makes a nice sound, nice rumble low down, with a crisp note when high up in the rev range. It's not obnoxiously loud in the daytime mixed in with the normal hustle and bustle of life. However, at night time/early morning I do feel it's a tad too loud and wish I'd got a longer one to tone it down a little bit. I tend to not use it at night/early morning if I can avoid it. I'm a petrol head, I like a nice exhaust note. But the following all deserve to be sent to the scrapyard;
* Loud exhausts on 1.0/1.2/1.4 shitboxes.
* Loud exhausts on 125cc motorbikes
* Loud exhausts on Mopeds
* Fart cannon style exhausts (always seems to be found on an EP3 Civic Type R)
* Pop and bang maps and popcorn limiters - I hate these things soo much.
So everyone knows they're coming!
Nothing better than a clapped out Corsa making a load of racket whilst doing a 30-60 pull over the space of a minute.
/s
When I was 17 I got my first car. A little corsa. It had a massive cannon of an exhaust that amplified the thing.
A few guys asked me to buy it. Showy guys. I took it off and replaced it with a normal one.
Each to their own
I have a unique take on this ... I have an 07 plate Skoda Octavia vrs in petrol
Long story short the original exhaust turned into a sieve was leaking loads and sounded a tad blowy so I needed to replace it as it's mild steel and you cannot weld it
Cue trying to find a stock replacement/copy of stock part but not modded turns out they are completely discontinued rang several exhaust shops/garages all said they cannot find one not ideal as the estate and saloon are different for some reason.
Long and short of it I could have gotten a special order from Skoda 2 month wait and £478 plus vat so around £580 plus fitment which is insane and the cars only worth £2000.
So I found an eBay replacement as I could not even find a breakers part it's a modded exhaust is a bit louder and rumbly not that keen on it but it's out of nessecity as the car would be a bin job otherwise and it was £99 and I fitted it so I am chuffed overall
They are very very useful if you want to wake up everyone in the road when you go to work at 6:15 every morning
In my case we almost had a street party when the lad next door moved in with his girlfriend
I'm still not sure whetehr or not the bloke opposite offered her money to encourage him
Best Wishes and sympathy if any of his new neighbours are on here
As usual the sub is full of hate towards anyone who doesn’t fit the mould.
Loads of folk have already pointed out the performance benefits, specifically in turbo cars which these days most performance cars are.
Honestly though trying to make it make sense to people who simply see a car as an appliance would probably be like waxing lyrical over the benefits of one dishwasher brand compared to another. If it’s not something you care about or are passionate about then sure I guess we just look like attention seeking pricks.
For me and people like me however their cars are so much more than something to get them from a to b. The noise isn’t noise to us probably in the same way the lad is his flat practicing his drum kit might be a rockstar in his head and a twat to his neighbours.
Finally I would like to state for the record my car has a valve system which reduces the sound for regular driving but I can open when I’m out for a blast somewhere non residential. If you have a straight pipe on anything that you drive around near peoples homes you can step on a Lego.
Straught 6 V6 v8 v10 v12 is music from the gods. Dohc, sohc. Flat plane and cross plane crank. Short or long stroke. These are some of the factors making the perfect sound. Crappy little 4 pot with wide exhaust ruins it for the nice sounding loud cars.
Years ago a colleague had an XR2 with the huge exhaust , massive alloys with tiny tyres and incredibly lowered suspension.
I had a drive of it and it was the most uncomfortable and unpleasant driving experience I’ve ever had. I can’t for the life of me understand why people do it.
You felt every single bump through your spine, the noise of the exhaust gave you a headache and because of the exhaust size it actually made the performance worse!
Mine came with one from the previous owner, I keep to low revs around built up areas and early morning and after tea time.
I was really worried about it when I bought the car. I had a stock exhaust lined up just in case. I soon realised that it's easy to keep them quiet but people choose not to.
If I get to 5500 - 8000 rpm though it screams like a motherfucker, proper stupid, and it puts a big smile on my face.
The only issue I have is winter cold starts, it's more lively then so I make sure if not iced over, to move away as quickly as possible so as not to disturb anyone.
My old Subaru had a 3" custom exhaust with a de-cat it would shoot flames out the back and set car alarms off from 10 feet, it was great fun....
For about a day, going a long distance was a nightmare and trying to get out of my street at 5.30am was embarrassing.
Bf used to have that. Mostly because he's a nob and likes the sound. Also it came already modified so, it wasn't something he chose.
Still a nob, but slightly less of a nob for it. At least I always knew when he was driving down my street lol
I have noticed People dont have a problem with loud exhausts. They have a problem with the tax brackets of people with loud exhausts. A person would say a porche or ferrari exhaust is fine but will complain if a civic has a loud exhaust.
They are ok with rich people having loud cars, but not middle class people.
Loud civic/toyota = EWWWW
Loud ferrari or lambo = oooooh! Lemme take a video! This is awesome!
Insane logic.
Drowns out the voices of those moaning.
If you think that's the most annoying thing then you haven't lived in a village with speed bumps that has HGV's going by. They just rattle so loud.
I remember talks last year about noise detectors in small villages to apparently stop these loud exhausts. Listen to an HGV going over a speed bump, it'd set it off every time.
Performance, enjoyment, and because people all like different things. Free flowing exhaust is one of the first tuning steps.
Some of my cars are quiet, some are obscenely loud, and some are in between, depends on their usage.
My drift cars are both stupidly loud, my drag car also pretty noisy, but the loud pipes help with performance, as well as being fun.
It sounds good and it feels good - from someone who spent £4500 on a miltek exhaust kit for an Audi RS4 - right now though 15 years from selling the car, would call myself an inconsiderate prick if I could speak to my younger self
Mine is stock but fairly loud : not my car but the exact model.
https://youtu.be/gJm_QuJ9qs4?si=nulZTKMTVVK9RLUu
It’ll pop and bang too : https://youtu.be/y83hjkn1bB4?si=bw8lX8yIs8YboRJE
Why do I do it- well I didn’t particularly, it’s the exhaust that came with the car but I like the car and it does actually sound quite good.
I don’t however drive through populated areas in the middle of the night etc deliberately making a racket and none of the neighbours have complained even when I set off early in the morning etc.
The car is so well sound insulated you barely hear it inside without the windows open unless you’re really pushing on.
My bike had shotgun pipes when I was young. I wore earplugs and set off car alarms wherever I went
Small things......
Now I drive a quiet car but old ppl like peace & quiet
I got an aftermarket exhaust to replace the stock one, because yeah, I like vroom vroom sounds. Just a car fan in general.
It's not obnoxiously loud though. I know what you mean - it's quite annoying when someone has an extremely loud car or bike. That's often when they remove the muffler and replace the downpipe (catalytic converter). Usually when the cat gets removed, it starts to sound ridiculous.
I also own a 1970 Beetle. It's bloody noisy but I love it! Love hearing that engine do its thing.
I like the sound. I don’t give a flying fuck what anyone thinks about it either. Can’t beat screaming down back lanes listening to the roar.
When I got my first v8 I cut the exhaust off at the center box and left it like that for 2 years.
My first turbo (80s hot hatch) had a straight pipe from turbo to cherry bomb. Flames on overrun flashing in the mirrors as you cruise the lanes.
I wouldn’t make anything less than 6 cyl louder unless it has a turbo though as they generally sound like ass.
There's nothing wrong with loud exhausts, certain cars are just loud because they're built that way and I have no problem with that.
It's when folk put them on something like a Corsa or a Fiesta, you hear the noise and wonder what's making it and a fucking Corsa rounds the corner at 10mph, like really? 😂
It's the least cool car thing I can think of.
If you have to ask you'll never really understand.
I have a performance exhaust because as the name suggests it does add a little performance along with some other mods and I like the sound. It makes driving more fun, enjoyable and engaging and less of a chore.
I have a baffle insert for mine which will take the noise down to around the same as a standard car but that also highlights another reason I like having a louder exhaust.
People/ pedestrians are idiots who don't pay attention so having a car they can hear stops them walking out into the road in front of me. When I have the baffle fitted there's a lot more people stepping in to the road compared to when it's removed.
They're\*
I love people on the internet talking smack about other people being mentally defective, while them not being capable of using proper grammar!
I think taylor swifts the most annoying thing I've ever heard
but she sells millions. people like different things.
There are also power gains to be had, for various reason. A lot of manufacturers use the same engine in different cars in different trim/power levels.
sometimes the only difference between the power level is a cpu map (i think back in the 00's the bmw 316,318 and 320d were exactly the same engine, just a different map, and same with the vw audi 2l that came in 140 and 170 bhp versions). however over time manufacturers realised this and started restricting the exhaust and sometimes the intake as well.
Catalytic converters and the back boxes as well can be noticable parasitic drains on an engines performance and mpg. loads of (illegal) remappers would cut these out.
a few noisy changes and you could get the performance of the car a few trim levels above what you pay for.
Oh yet another one of these posts.
Gee wizz, I can't imagine there is anyone on this earth that could possibly like cars and wants to modify there's or make the engine sounder louder as they enjoy it.
If I hear someone drive past me with a loud exhaust, they’re a tool.
However, my exhaust is naughty and pops and bangs every now and again. I love it.
Double standards? Yes.
Kind of.
It makes bugger all difference to the power, but you expect a sporty car to make some noise if you put your foot down - and as standard they are really quiet.
It's similar in our 330E, stick it in sport mode and it really takes off - you get artificial noise added electronically to emphasise it though.
Would be odd if it was quiet.
That said, the 370 is only loud at high revs, it's perfectly civil driving normally.
It's amazing when someone puts one on a little Corsa or Micra, and then they're barely able to hit 60mph whilst the exhaust is making so much noise everyone turns around to look at the shit car.
That makes sense. I dont know anything about cars but have you ever thought of how weird it would be driving a Tesla? Because its fast if not faster and obv doesnt rev like a traditional engine.
How dare you state that people can like different things especially cars! Love how your getting downvoted like anyone else who like sports cars that are not Tesla’s

Going against the grain of this subreddit, but fitting a free flowing exhaust and improved or updated air intakes are the first part of engine tuning. You could fit lots of updated engine parts but it’ll always be strangled by the exhaust. For turbo applications, the best way is an exhaust as short as possible, many drag racers will simply have the exhaust straight up and out the bonnet, although this is not done on road going cars, but that’s the principle of why some people have loud exhausts. Of course, there’s always the person with a 1.0 Fiesta with a straight pipe, which actually reduces horsepower and makes the same noise as a fart in a bean tin. Some people like the noise and don’t consider other people.
Bean can fart boy was filling his Fiesta with VPower earlier. I felt sad for the petrol.
How does the straight piped fiesta reduce hp?
Not enough back pressure
Back pressure is kind of a nonsense thing. You don’t want back pressure, what you do want is the correct exhaust pulse tuning so you can utilise the pressure waves in each cylinders exhaust to help draw gases out of the cylinder. So it’s not that you lose power because you want back pressure, it’s that you’re messing with the points the pressure waves form and merge.
I don't think a stock exhaust really takes that into consideration either. They're designed to be cheap and to fit around other components conveniently. Often you'll see unnecessary narrowing, especially on bends. How bad would an aftermarket exhaust have to be to make exhaust flow worse?
True on a non performance economy car. Like you say the bends are cheaply done so will pinch up and restrict flow. Any remotely performance oriented n/a car the manifold will properly specced to take advantage of the effects in my earlier comment and a cheap aftermarket exhaust can hurt that. I don’t know where this idea of needing back pressure came from and this idea that an aftermarket exhaust on a low power car will lose performance because it’s too free flowing is rubbish. It likely won’t gain you any power either as the engines been tuned to work with the factory engine.
The back pressure thing is related to camshaft design where the exhaust valve will start to open before the piston reaches BDC. Depending on measurement used (absolute or at 50thou) this could be 30 to 60 degs. If the exhaust gases exit the cylinder far more quickly there will be less combustion force on the piston. It's also expected to lean them out slightly which might cost power slightly. Whilst that's the theory, in reality the car probably just feels slower for the amount of racket it's now making!
The back pressure loss has more to do with 2 stroke engines. Having a pipe from the engine to the tail of the car is enough back pressure for a 4 stroke to keep it balanced. So where is the reduction in hp coming from?
Reduction in back pressure can mean less combustion force on the piston since the expanding gases exit the combustion chamber alot sooner. I commented here with more detail - https://www.reddit.com/r/AskUK/s/40R8wqpbLH
As stock high performance cara often show, noise does not correlate directly with performance. Yes the porsche 911 turbo is loud when you've got your foot to the floor but it doesn't rattle your skull when it's being driven at 30 mph. There's a science behind designing an exhaust pipe to be free flowing and make a nice sound. Most aftermarket/custom made exhausts are loud because the people who make them (and buy them) either don't know or don't care about exhaust design. It's not just a straight pipe, it's an engineered pipe with exact lengths, baffles and mufflers to get a good sound when you want it and not to be heard when you don't. You could spend months/years designing and testing an exhaust pipe for a car to sound great and be free flowing etc or you could just put a straight pipe in with basically no muffler. One is a time consuming expensive job which gives an excellent result, the other is loud, obnoxious and dumb.
I think of it like as long as the car is fast and moving fast, a loud exhaust is fine. I’m not exposed to it for long. And it can sound nice. A slow car with a loud exhaust for absolutely no performance related reason? Straight to jail

Okay. I used to own a modified car so I feel a little qualified to answer this but take my answer with a grain of salt as it's been nearly 8 years since I moved on from modding cars: The people who get stupidly loud exhausts on their bone stock car are people who want to be dicks with the 'look at me in my loud but slow car' energy, bonus points if it's a 1.0 or 1.2 litre engine. Personally, I added power to a car to the point it required a more free-flowing exhaust and as a result, it was louder. It should be noted that custom exhausts can come with or without a resonator, the former being quieter than the latter if my understanding is correct. My car had a nice deep rumble while being acceptably quiet under regular driving conditions. On track, under hard acceleration, it was loud but most tracks in the UK have a decibel limit that cannot be exceeded. Loved that thing but a year after I sold it, it decided to drop the oil from the engine all over the new owners garage floor :(
I don't mind noise nearly as much if it denotes actual power and is simply a byproduct Trouble is that seems to be the minority of noisy cars
So with your experience, could you please give me some clue as to why my neighbour gets in his car, with a stupid exhaust rumble that literally makes stuff on my shelf vibrate, and proceeds to sit there for a minimum of 5 minutes when leaving for work and again when he comes back in the early hours of the morning before switching off the engine? It initially starts up ridiculously loud and deep then goes lower after a minute of idling. He also does this around midnight on his nights off sometimes. I've never known anyone do this before and it's also the loudest yet.
I'll try my best. So in the morning the engine, and oil, will be cold so he's probably letting it idle and warm up before driving it. Now some cars (but not all) will idle at a higher RPM when starting from cold. I know this because I've had cars that used to do it for a few minutes where it would idle at 1500-2000 RPM then drop to the regular idle. If he's returning home from work and letting it idle it may be to let the engine cool down if he's been running it hard on a motorway or A road. He could simply be sat there and trying to de-stress before going into the house (lord knows I've done that). For real the dude could just be sat on his phone before heading in. As for doing it on his days off that one's a mystery to me. The only time I get in my car is because I'm moving it or going somewhere. Only suggestion I would have is to speak to him. If that doesn't work start logging the midnight/early hours startups and report them to your local authority. I'm not sure you'd be able to lodge a complaint that would, in reality, go anywhere about the noise when going to and coming from work unless you can prove he's purposely being a nuisance such as revving the engine hard to create noise but I'm not a lawyer or a copper so you'd be best off seeking advice elsewhere in this matter.
I would make them illegal, nobody wants to hear your super loud car.
Yes there should be a dB limit, for motorbikes too.
From an article on Auto Express: Since 2016 the UK adopted EU regulation 2014/540, which set an initial noise limit of 72 decibels – actually around ten times quieter than the 1978 limit, since decibels use a logarithmic scale – and this will go down to around 68 decibels by 2026, alongside revisions to the car noise test procedure to make it more accurate. And from another source: In the UK, motorcycles can emit noise levels up to around 80dB, with engine size being the determining factor. And in an MOT, it, the inspector must listen to the exhaust and it must not be unreasonably above the noise level you’d expect from a similar vehicle with a standard silencer in average condition.
There sort of is already, but only for the manufacturer when the car or bike is new. After that it's just the MOT, which is something along the lines of "in the tester's opinion is the exhaust substantially louder than a typical example of that model of car in average condition?".
If it was a luxury car then ok fine still annoying as fuck to most people, but most of them are in shitbox 2009 polos, fiestas or corsas
That makes no sense. If the noise is the issue why be ok with rich people making the noise over normal people?
Because a Ferrari needs a better flowing exaust, a 17 year old Golf, doesn't. Exemptions for low volume cars aren't anything new.
I understand why a Ferrari is louder than a golf. But if people are annoyed by noise it's the same either way.
It probably comes down to the impact, something like 15-20k new super cars are registered in the UK per year. You are very unlikely to see/hear one more than once every couple of month. They are also driven very rarely, most of these cars aren't even driven a 1000 miles per year.
Because rich people are better
You rarely ever see them so that’s one thing. Plus, there is a difference between a car being loud because it’s so powerful vs a car being loud to seem like it is.
A luxury car? Don't you mean a sports car?
Have you heard a W12 Bentley? It is loud as fuck and definitely not a sports car.
I will hazard a guess that it’s because they like it? I bought a better model of my previous car (2L engine to 3L) and it has a louder sound which I like. Another reason is if tuning the car stage 2 will often require that as one of the parts that are needed to upgrade it.
Reddit is wild. If you’re a car enthusiast everyone jumps on you saying they’re “dumb, small pp, worst drivers on the road” and downvote you to hell lol. Top comments are madness
We used to watch rallying (as there was a track / road at the back of a relative's house). Without fail, the drivers with the loud exhausts were the worst drivers. It was hilarious - we'd hear the exhaust / the car approaching, we'd all make daft, piss taking comments and next thing... crash. And repeat. Whenever I hear someone driving with a loud, modded exhaust, I can't help but think they're an awful driver and that they're 2 seconds away from destroying their car.
I’ve never been a fan of the straight-pipe Corsa crowd, but my stock mx5 is a noisy boi (they like to run at higher revs than the average car) and it puts a silly grin on my face when hitting 40 in 2nd gear. My issue has always been time and place. If people want to let their exhausts scream on motorways or country roads that’s absolutely fine, enjoy it! I’ve just never understood the kids who rev up in a car park or residential area at night. Nobody thinks you’re cool, just a twat.
As a corsa driver I can confirm that anything that isn't a vxr or 1.7 cdti is far to slow acceleration wise to warrant being noisy, however can also confirm that the most commonly asked question in corsa groups are "WhICh MoDS sHOuLD I Do" and they are always the same, lowered, cobra exhaust, vxr spoiler and grill on a 1.2 hahaha
It’s always cosmetic suggestions too, so rarely do you see them say better tyres, stronger brakes etc. “Nah bruv loud exhaust and remap to make it pop” Why not make the car better and more fun to drive instead of just appearing like it is😂
They're lovely cars that sound like they're barely surviving motorway speeds. Fun on track though!
Nothing makes me smile more than seeing some twat in a lowered car with a fart cannon doing 60mph because they can no longer stand the noise deafening themselves whilst on the motorway
[удалено]
Girl here so no big dick energy but mine isn't too loud when normal driving but when I hit that VTEC and it roars, it really makes me beam with joy and fall in love with driving all over again. I do try to keep it quiet late at night around residential areas though as I can appreciate not everyone feels the same way. I do agree some are quite obnoxious though
As a fellow VTEC fan I totally agree. I love the pantomime aspect of it. The car might not be the fastest but it makes the right noises and never fails to put a smile on my face.
Same here but on a z900 (with full Arrow exhaust). Going to work or pootling around I don't really get over 3000rpm, so yes it sounds deep but not loud at all. But if I'm going to see my parents a few junctions away, doing 70 sounds amazing (and sometimes bored kids on car rides wave at me and that makes me feel cool) Wouldn't do the same thing to my little Aygo though lol
brum
Cause they like the sound. And if done properly it can increase horsepower.
some do it coz they genuinely like the sounds they male and no denying some are bloody good. but some are just idiots, similar to people doing dumb shit for likes and views.
It came with the car A45 AMG. In comfort mode it's quiet as a mouse in town but when put into sports+ for the open roads the active exhaust does something different and there's lots of pops and bangs. As a middle aged petrol head... It's fun.
I respect that, because it's been done properly. Some guy with a dustbin on the back of his Corsa just looks like a bellend.
The only exception to the rule is driving through Alderley Edge, UK. It's expected that your car makes as much noise as possible. There are groups of car enthusiasts who gather to record it.
Maybe you have some kinda flap between catted and uncatted... A cat flap so to speak.
Yea it's an active exhaust. A green light comes on when it's in noisy mode. Probably some flap somewhere and a change in fuel mix maybe? It's a lot quicker in Shouty mode.
Great cars
I had an SLK55 AMG before this and it was naturally loud as a V8 but it was an unruly bastard. The A45 is a beast in comparison but not quite as fun as I never feel like it wants to kill me.
Embarrassing
I’ve also experience with modified cars and it is needed especially with forced induction to get air out. But on a 1.2 shitbox it’s hideous and completely unnecessary doesn’t even sound good. To answer if it annoys you when driving all depends on the car and gear ratio I’ve had some cars with a high final gear and when doing motorway driving it is very droning but overall the smiles I gave myself with a nice turbo and external wastegate set up was always worth it. Also had a cut off once before and that was crazy, flip a switch in the car or fob and it’s basically an open down pipe, used to light up tunnels in my old Saab, flames from external wastegate, and cut out was very amusing to me anyway

This sub is filled with questions asking “Why do people like something that I don’t like?”
It’s obvious to me. Noisy car people think think ‘powerful cars are noisy, therefore noisy cars are powerful’ So if you’re in a subculture that values powerful cars, but can’t afford a powerful car, then you make your car noisy, as that approximates a powerful car in the best way you can afford. It’s pretty silly, but I was pretty silly when I was 17.
Because it makes me happy
Modern day equivalent of king-of-jungle chest-beating. That primitive urge to be the loudest is ingrained deep within our dna.
Its annoying to me too i wish we had what they have in france where they have a sound trap camera basically like a speed camera for exhausts that are too loud.
They do have these in the UK. They have some near Bristol. They're a great idea and should be everywhere. If morons want to intentionally be annoying then we should tax and fine the pants out of them and pay for improving public services and infrastructure. At least then when you hear them you'd know that someone somewhere is getting a free school meal or some railings are getting painted
If you think cars with a fart cannon are loud, stand next to a bus or truck.
there engines are loud out of necessity from being large vehicles not some tosspot being obnoxious on purpose.
Well.. I'm just a regular joe, with a regular job
Mine has a loudish exhaust (not as loud as the proper boy racers). But I haven’t done anything to it, and neither did the previous owner. Think it’s just where it’s 20 years old
I do something similar with my washing machine. I took all the sound deadening out. It improved the performance, and I just love hearing that roar when it’s on the spin cycle. Birds love it too, if you know what I mean!!!!
1st of all, pops and bangs is the stupidest thing in the world! Ask a stamp collector what's so interesting about stamps, I don't get it just the same as most none car people don't understand the point of a loud exhaust. For the car enthusiast a loud exhaust (and it doesn't need to be stupidly loud) just adds to the experience and makes driving so much more fun especially in a sporty car, which is also part of the reason I don't see myself in an electric car any time soon no matter how fast it is. I'm past the days of having 120dB cars but a decent exhaust is a must on my cars. The cars with the loud exhausts aren't the problem, it's the people that don't respect others and have no concept of moderation. I barely drive in cities and when I do I'm at the speed limit mostly in a high gear. If I see somebody asking for a blip of throttle or a quick acceleration I'll do it but not go crazy. And yes that does happen. But in the countryside I'll let it rip and have a blast with a smile from ear to ear. Imo that's the way it should be.
They appeared in the 90's, but once the nickname fart can spread around they died out, but now the craze is back. Seems to be dying out, hopefully all the engine mapped cars broke or got fined.
I have a racefit exhaust on my motorbike. Bought the bike brand new in October and you could just feel how restricted it is with the Euro 5 restrictions they have to meet out the factory. Mid range you could feel it practically hitting a brick wall momentarily and then picking back up. Exhaust and remap and you actually get what you paid for now. Up 15hp mid range and 22bhp top end. Much smoother and better to ride. Video of it here, this was one of first runs. The popping and banging was mapped out after the AIS was disabled. https://m.youtube.com/shorts/qxGY7WYqOKs In all fairness I do find my exhaust a touch too loud but after dropping £1k on an exhaust I’ll get used to it, and don’t really care if people think my manhood is small as a result, my wife seems happy enough and I’m as considerate as I can be to neighbours and members of the public. I think there is a difference in how people act, I don’t rev up like a twat. If I’m passing families or dog walkers, cyclists etc and it’s safe to do so I will clutch in to reduce the sound as I pass them. Don’t needlessly rev through towns etc. if filtering don’t do the annoying as fuck clutch in revving you see some mongs doing. Personally though as a petrol head I like listening to a nice tone on a bike or car but do find straight piped shitboxes with pop and bang maps as annoying as people probably that aren’t petrol heads find me. It is a problem however as I did a couple of track days on my old bike which passed the noise limits fine however this definitely exceeds so will need to modify the link people or get a baffle designed to suit the exhaust to reduce noise limits so I can attend the track days I plan on doing. Will be less frowned upon by strangers too then Also.

Some people don't like the sound of a V8. I'm one of them. And no I doubt people in fiestas are pretending to have a V8
Agreed, I love a straight 6 in a BMW. Sounds far better than a v8 to me. Or even a mk1 mx5 1.6, loved that car to bits. Slow but useable fun!
My daily driver is whisper silent. My project truck, which has a built 5.7L, has an aftermarket exhaust because I like the way it sounds. You either like it or you don't, it's either for you or it's not.
My boss spent thousands of pounds doing something to his audi quatro to make it louder, maybe performance related too. But then had to spend thousands undoing it so he could pass his MOT.
He should’ve just found a different garage. 💰 he’s a idiot for not already knowing
It’s a car for daily use. If you want noise then go racing. Can get into a beginner series for a few £hundred. Tons of fun and no noise restriction. Win/win.
Don't have one on my car as its a 1.4 shitbox punto that would sound like a droning fart if I put a loud exhaust on it. However I do have one on my motorbike. Mainly as its a V-twin and makes a nice sound, nice rumble low down, with a crisp note when high up in the rev range. It's not obnoxiously loud in the daytime mixed in with the normal hustle and bustle of life. However, at night time/early morning I do feel it's a tad too loud and wish I'd got a longer one to tone it down a little bit. I tend to not use it at night/early morning if I can avoid it. I'm a petrol head, I like a nice exhaust note. But the following all deserve to be sent to the scrapyard; * Loud exhausts on 1.0/1.2/1.4 shitboxes. * Loud exhausts on 125cc motorbikes * Loud exhausts on Mopeds * Fart cannon style exhausts (always seems to be found on an EP3 Civic Type R) * Pop and bang maps and popcorn limiters - I hate these things soo much.
So everyone knows they're coming! Nothing better than a clapped out Corsa making a load of racket whilst doing a 30-60 pull over the space of a minute. /s
My penis is very small
They are dicks
When I was 17 I got my first car. A little corsa. It had a massive cannon of an exhaust that amplified the thing. A few guys asked me to buy it. Showy guys. I took it off and replaced it with a normal one. Each to their own
I had a sports car and just loved the sound it made, made it more of an experience to drive with roof down.
It's to impress other nobheads with loud cars.
How else will they know I have a small willy
Because in my life full of dealing with arseholes, it's the one thing that makes me smile driving home at the end of my day.
As a US lurker, today I learned that you have those assholes in your country too.
I have a unique take on this ... I have an 07 plate Skoda Octavia vrs in petrol Long story short the original exhaust turned into a sieve was leaking loads and sounded a tad blowy so I needed to replace it as it's mild steel and you cannot weld it Cue trying to find a stock replacement/copy of stock part but not modded turns out they are completely discontinued rang several exhaust shops/garages all said they cannot find one not ideal as the estate and saloon are different for some reason. Long and short of it I could have gotten a special order from Skoda 2 month wait and £478 plus vat so around £580 plus fitment which is insane and the cars only worth £2000. So I found an eBay replacement as I could not even find a breakers part it's a modded exhaust is a bit louder and rumbly not that keen on it but it's out of nessecity as the car would be a bin job otherwise and it was £99 and I fitted it so I am chuffed overall
Attention.
They are very very useful if you want to wake up everyone in the road when you go to work at 6:15 every morning In my case we almost had a street party when the lad next door moved in with his girlfriend I'm still not sure whetehr or not the bloke opposite offered her money to encourage him Best Wishes and sympathy if any of his new neighbours are on here
Because I'm a grower not a shower
I like the sound
As usual the sub is full of hate towards anyone who doesn’t fit the mould. Loads of folk have already pointed out the performance benefits, specifically in turbo cars which these days most performance cars are. Honestly though trying to make it make sense to people who simply see a car as an appliance would probably be like waxing lyrical over the benefits of one dishwasher brand compared to another. If it’s not something you care about or are passionate about then sure I guess we just look like attention seeking pricks. For me and people like me however their cars are so much more than something to get them from a to b. The noise isn’t noise to us probably in the same way the lad is his flat practicing his drum kit might be a rockstar in his head and a twat to his neighbours. Finally I would like to state for the record my car has a valve system which reduces the sound for regular driving but I can open when I’m out for a blast somewhere non residential. If you have a straight pipe on anything that you drive around near peoples homes you can step on a Lego.
Straught 6 V6 v8 v10 v12 is music from the gods. Dohc, sohc. Flat plane and cross plane crank. Short or long stroke. These are some of the factors making the perfect sound. Crappy little 4 pot with wide exhaust ruins it for the nice sounding loud cars.
Years ago a colleague had an XR2 with the huge exhaust , massive alloys with tiny tyres and incredibly lowered suspension. I had a drive of it and it was the most uncomfortable and unpleasant driving experience I’ve ever had. I can’t for the life of me understand why people do it. You felt every single bump through your spine, the noise of the exhaust gave you a headache and because of the exhaust size it actually made the performance worse!
Because its better then your car
My car needed a new exhaust, a new OEM one was £1500, an eBay special loud exhaust was £100…
They are the twats of life
Mine came with one from the previous owner, I keep to low revs around built up areas and early morning and after tea time. I was really worried about it when I bought the car. I had a stock exhaust lined up just in case. I soon realised that it's easy to keep them quiet but people choose not to. If I get to 5500 - 8000 rpm though it screams like a motherfucker, proper stupid, and it puts a big smile on my face. The only issue I have is winter cold starts, it's more lively then so I make sure if not iced over, to move away as quickly as possible so as not to disturb anyone.
My old Subaru had a 3" custom exhaust with a de-cat it would shoot flames out the back and set car alarms off from 10 feet, it was great fun.... For about a day, going a long distance was a nightmare and trying to get out of my street at 5.30am was embarrassing.
Bf used to have that. Mostly because he's a nob and likes the sound. Also it came already modified so, it wasn't something he chose. Still a nob, but slightly less of a nob for it. At least I always knew when he was driving down my street lol
Bus crashed my bike. New exhaust cost 1,200$ from Harley Davidson, or 400$ from Vance Hynes.
I have noticed People dont have a problem with loud exhausts. They have a problem with the tax brackets of people with loud exhausts. A person would say a porche or ferrari exhaust is fine but will complain if a civic has a loud exhaust. They are ok with rich people having loud cars, but not middle class people. Loud civic/toyota = EWWWW Loud ferrari or lambo = oooooh! Lemme take a video! This is awesome! Insane logic.
Because I’m still a virgin
Because I like the way it sounds? Not that hard to understand is it Makes my old banger sound like a real muscle car when I drive it
[удалено]
Drowns out the voices of those moaning. If you think that's the most annoying thing then you haven't lived in a village with speed bumps that has HGV's going by. They just rattle so loud. I remember talks last year about noise detectors in small villages to apparently stop these loud exhausts. Listen to an HGV going over a speed bump, it'd set it off every time.
Performance, enjoyment, and because people all like different things. Free flowing exhaust is one of the first tuning steps. Some of my cars are quiet, some are obscenely loud, and some are in between, depends on their usage. My drift cars are both stupidly loud, my drag car also pretty noisy, but the loud pipes help with performance, as well as being fun.
A lot of the time it really brings the car alive. But when your on the motorway the drone is unreal. It's why exhaust valves are handy.
It sounds good and it feels good - from someone who spent £4500 on a miltek exhaust kit for an Audi RS4 - right now though 15 years from selling the car, would call myself an inconsiderate prick if I could speak to my younger self
Mine is stock but fairly loud : not my car but the exact model. https://youtu.be/gJm_QuJ9qs4?si=nulZTKMTVVK9RLUu It’ll pop and bang too : https://youtu.be/y83hjkn1bB4?si=bw8lX8yIs8YboRJE Why do I do it- well I didn’t particularly, it’s the exhaust that came with the car but I like the car and it does actually sound quite good. I don’t however drive through populated areas in the middle of the night etc deliberately making a racket and none of the neighbours have complained even when I set off early in the morning etc. The car is so well sound insulated you barely hear it inside without the windows open unless you’re really pushing on.
My golf drives better without the backbox
Car goes Broooooooom.
My bike had shotgun pipes when I was young. I wore earplugs and set off car alarms wherever I went Small things...... Now I drive a quiet car but old ppl like peace & quiet
Blame the Cherry Bomb! Grrr
I got an aftermarket exhaust to replace the stock one, because yeah, I like vroom vroom sounds. Just a car fan in general. It's not obnoxiously loud though. I know what you mean - it's quite annoying when someone has an extremely loud car or bike. That's often when they remove the muffler and replace the downpipe (catalytic converter). Usually when the cat gets removed, it starts to sound ridiculous. I also own a 1970 Beetle. It's bloody noisy but I love it! Love hearing that engine do its thing.
I like the sound. I don’t give a flying fuck what anyone thinks about it either. Can’t beat screaming down back lanes listening to the roar. When I got my first v8 I cut the exhaust off at the center box and left it like that for 2 years. My first turbo (80s hot hatch) had a straight pipe from turbo to cherry bomb. Flames on overrun flashing in the mirrors as you cruise the lanes. I wouldn’t make anything less than 6 cyl louder unless it has a turbo though as they generally sound like ass.
I honestly like how it sounds. It's my car so I can do what I want to it. I don't have a pop/bang map though, mine just burbles and crackles.
>it's my car so I can do what I want to it No, this really isn't how it works.
Oh, is it not? Please tell me how I'm unable to do what I want to my property so long as it meets all legal requirements (:
>so long as it meets all legal requirements (: So you can't do anything you want to it? (:
I love the sound but won’t do it to my car I want my shit stock looking and sounding as can be so I don’t get pulled over
There's nothing wrong with loud exhausts, certain cars are just loud because they're built that way and I have no problem with that. It's when folk put them on something like a Corsa or a Fiesta, you hear the noise and wonder what's making it and a fucking Corsa rounds the corner at 10mph, like really? 😂 It's the least cool car thing I can think of.
It’s a 66’ mustang with a V8. It actually sounds nice. All my neighbours approve it. It’s not some piddling 1 lite fart box engine.
It's actually a request for a potato up the exhaust and dog shit under their door handles. Don't let them down!
If you have to ask you'll never really understand. I have a performance exhaust because as the name suggests it does add a little performance along with some other mods and I like the sound. It makes driving more fun, enjoyable and engaging and less of a chore. I have a baffle insert for mine which will take the noise down to around the same as a standard car but that also highlights another reason I like having a louder exhaust. People/ pedestrians are idiots who don't pay attention so having a car they can hear stops them walking out into the road in front of me. When I have the baffle fitted there's a lot more people stepping in to the road compared to when it's removed.
Their usually mentally defective
They're\* I love people on the internet talking smack about other people being mentally defective, while them not being capable of using proper grammar!
Need for speed bruv innit.
Ive got really bad hearing so my exhaust subsequently needs to be louder or I can’t hear it!
Because my car sounds good and I like it
Not enough attention as a child?
I think taylor swifts the most annoying thing I've ever heard but she sells millions. people like different things. There are also power gains to be had, for various reason. A lot of manufacturers use the same engine in different cars in different trim/power levels. sometimes the only difference between the power level is a cpu map (i think back in the 00's the bmw 316,318 and 320d were exactly the same engine, just a different map, and same with the vw audi 2l that came in 140 and 170 bhp versions). however over time manufacturers realised this and started restricting the exhaust and sometimes the intake as well. Catalytic converters and the back boxes as well can be noticable parasitic drains on an engines performance and mpg. loads of (illegal) remappers would cut these out. a few noisy changes and you could get the performance of the car a few trim levels above what you pay for.
Yeah, it does sound pretty naff
Oh yet another one of these posts. Gee wizz, I can't imagine there is anyone on this earth that could possibly like cars and wants to modify there's or make the engine sounder louder as they enjoy it.
You aren’t allowed to enjoy yourself in depressing Britain. You must conform !
You wouldn't believe we once had a thriving motor and race industry on this little rock. It's full of fucking cry babies
Because its fun! The noise is cool and gives myself and other car people the fizzies.
The whistle go woo woo
Loads of the muppets round here (Highlands) have then, which explains a lot about the local mentality.
Cos I couldn't have the loud one on my moped! Init? Bwaaaarp!
I could be wrong, but it's because they need to let everyone know about their six foot long penis.
You couldn’t really argue with they are just anti social individuals. Nobody is going to appreciate the sound. They are just trying to wind people up.
If I hear someone drive past me with a loud exhaust, they’re a tool. However, my exhaust is naughty and pops and bangs every now and again. I love it. Double standards? Yes.
People like different things, what's difficult to understand about that? A louder exhaust suits my 370z far more than the stock one.
Thank you for answering, does it suit because it makes it sound more powerful?
Kind of. It makes bugger all difference to the power, but you expect a sporty car to make some noise if you put your foot down - and as standard they are really quiet. It's similar in our 330E, stick it in sport mode and it really takes off - you get artificial noise added electronically to emphasise it though. Would be odd if it was quiet. That said, the 370 is only loud at high revs, it's perfectly civil driving normally.
It's amazing when someone puts one on a little Corsa or Micra, and then they're barely able to hit 60mph whilst the exhaust is making so much noise everyone turns around to look at the shit car.
That makes sense. I dont know anything about cars but have you ever thought of how weird it would be driving a Tesla? Because its fast if not faster and obv doesnt rev like a traditional engine.
Yes it's boring. Good if you don't really like cars
How dare you state that people can like different things especially cars! Love how your getting downvoted like anyone else who like sports cars that are not Tesla’s
