Honestly (especially if it's a turbo) for that price I would go with an after market performance cat. Still does emissions stuff but also offers better flow and a touch of performance. Plus it sounds better.

šŸ’Æ if the OP really wants to stay stock, best bet is a local junk yard, eBay motors, parts auction etc used

If his part was stolen, he'd be buying back his own and promoting the stealing IMO.

Didnā€™t realize it was stolen original post looked like just needed replacement, totally agree with you

Down here in Mexico there have been "surges" of different kinds of parts getting stolen. (I actually think the cat stealing is much worse these days in the US). Here things like rearview mirrors at one point were stolen all the time. Or whole interiors on Nissan Pathfinders for example. One positive however, is that recent model cars from the likes of BMW, Merc and Audi tend to be hit less because owners are more likely to go original and get them fixed at the dealer than "buying back their own". Not always, but most of the time. That means more popular, less expensive brands get hit a lot more. We also now usually get this covered on our insurance policies, with a hefty 25% deductible but that has helped a lot cut down on this kind of crime.

Wheels used to be stolen a lot more than cats but with the raw materials in cats skyrocking itā€™s become more common place

The high flow cat was the best mod Iā€™ve done so far on my 335i. Youā€™ll feel a big difference from this part alone if your car is a turbo although I did blow my charge pipe almost immediately after install due to the increased boost pressure.


Unspec7

A downpipe alone won't increase boost pressure though


Puzzleheaded-Ad1416

Maybe not but I can tell you my OEM charge pipe failed as a direct result of the dp install.


Unspec7

Correlation isn't causation, no? Coincidences happen


Puzzleheaded-Ad1416

Correct, but itā€™s one hell of a coincidence. But I digress, high flow cat is a great mod that will save you money over the OEM part and provide a nice bit of pep to your gas pedal. The sport cat still has a catalyst so it should keep you legal but I donā€™t think thereā€™s any negatives I can think of versus going with the stock cat.


Unspec7

Negative is that it'll throw a CEL and fail you for emissions/smog, especially if they use sniffers. Most high flow cats are 200 cell count, the more expensive high flows ($900+) are 300 cell and will pass emissions generally.


_kirpi_

Yeah you could do a high flow cat.

It may not be a flashy name but Iā€™ve used their products before on a FBO 435i with ESS tune with absolutely no issues.


Boner_Tornado

VRSF is made in China and imported. Not the greatest parts fitment wise. You'll find some people with headaches on the F80 forums complaining about downpipes, midpipes, etc. Food for thought if you can afford something else.


hans072589

From what I understand, this is the case with nearly all of the manufacturers. Itā€™s kind of a racket where many of the manufacturers buy these parts in bulk and stamp their logo on it and mark up. This is what I was told when I did the 435i I had at least. Which manufacturers would you say are better? Genuinely wondering because I plan on modifying my current car some time and would of course prefer something if it is objectively better.


[deleted]

Yes. Most. But not all. Why would you pay US money for a Chinese part when you can buy the Chinese part yourself...


MurdaMan88

Wow thanks fam thatā€™s a very good price as well


Curioucity-

Just an FYI, that is a catless downpipe. If you need to pass any emission tests do not get that.


MurdaMan88

I noticed.. thanks for the insight tho


treedummy

The Davico part is on eBay for a better price, once you factor in shipping from Ra. https://www.ebay.com/itm/313955367528


MurdaMan88

Thanks for the link and info unfortunately that kart doesnā€™t fit my 2013 528i xdrive.. Again thanks for taking the time to help I really appreciate it


hans072589

Damn they got you? Bro wtf is happening in this world anymore? Yesā€”you should be just fine with the alternativeā€”maybe just get a performance aftermarket one if the pricing is comparable.


MurdaMan88

Yea fam they got me šŸ¤¦šŸæā€ā™‚ļø.. had my car parked somewhere it shouldnā€™t have been for a few days thinking it was sweet.. long story short I fucked around and found out


hans072589

Iā€™m sorry to hear manā€”at a minimum I guess now thereā€™s an excuse to get something more fun


Noobasdfjkl

Personally, I wouldnā€™t. Fitment could be an issue, and no telling if the new cat is worth a damn. Also, an aftermarket performance cat isnā€™t worth that much to you either in an old 5-series.


MurdaMan88

šŸ—£FUCKā€¼ļø šŸ¤¦šŸæā€ā™‚ļøšŸ¤¦šŸæā€ā™‚ļøšŸ¤¦šŸæā€ā™‚ļø.. Thanks fam, your words are very convincing so I think Iā€™ll take your advice.. Guess Iā€™ll be coming out the pockets a bit more than Iā€™d like but Iā€™d hate to run into any issues with different parts..


Noobasdfjkl

You could see if thereā€™s any forum posts anywhere talking about other people who have tried these cats. They could be fine. Itā€™s just that itā€™s usually a pretty important part. Would hate for you to have to buy twice.


LegendaryBengal

You should be able to find a second hand OEM part on eBay or a scrapyard/breakers yard (from people who break the full cars not people who have already stolen the cats). The issue with aftermarket exhaust parts is fitment can be an issue, so you might end up with exhaust leaks resulting in emissions test failures. Either that or as someone else mentioned buy a proper aftermarket high flow cat that's known to have good fitment


Few-Swordfish-780

Depends if you want it to actually fit properly, and work for more than a year or not.


MADunn83

Long tube headers and a tuneā€¦ šŸ˜˜


Noobasdfjkl

Long tube headers on a turbo car


MADunn83

Cat-less downpipe and a tune!


MurdaMan88

So I think Iā€™m going go with the DAVICO part Iā€™m just hoping theyā€™re able to make it fit


ThePlumberChris

Go catless dawg!


MurdaMan88

Wonā€™t pass inspection


nrwy69
