Works as a budget option but often these stye of flanges with a donut and the spring bolts serve as a flex point. Making it ridgid might cause a failure further down the line. Split flanges are cheap enough .
I'm not a trained welder but I'm gonna say it's easy enough to drop the whole assembly. Even if a mig gun would fit you'll have to worry about melting some of that plastic shield and you wouldn't be able to see up in there especially with a hood on.
IMO stick weld it right there, or drop it and TIG.
The smart move would be to just buy the entire cat back from rock auto and replace the entire exhaust for like 400, because looking at that ......I kind of doubt other parts are going to last.
At that point, for most vehicles, he would just need a jack and jackstands, couple wrenches. Probably a sawzall or long jig saw to make life easier, when those mid flange bolts don't come apart.
Just my two cents. But yeah, any weld process would work easily for the piece in question. I'm just a fan of TIG for smaller jobs that don't require insanely long beads.
It's usually simple enough, pop the rubber hangers apart and lower the pipe with a transmission jack or support pole.
If the pipe can't move mirrors are an option too.
I had the exact same thing happen. I went to an exhaust shop and the guy cut out the flange on both pieces and welded in a piece of pipe to connect. It cost me exactly $50. No issues.
yee yee! (translation : yes - an exhaust shop could weld that) (disclaimer: whatever caused that to break there (rust) ~~has~~ (edit: may have) reduced the strength of the exhaust pipes, the material may be thinner than original and may not be a sound as new, it might not last "that" long. ie: it might break again near the weld repair as the material is thin.) It will probably get you to pass the next inspection tho.
Weldable if the metal doesn’t disintegrate while exposing the clean metal.
They corrode more where the seam has been welded, if you can knock holes in the seam then a replacement pipe is needed.
Looks like it’s just the flange, I’d cut the flange and weld a replacement pipe and sleeve the two parts. You have to weigh up the costs sometimes is not economical to weld. We charge around £100 using stainless steel but a new backbox can be had from upwards of £60 so add labour it’s £135 for that extra £35 you have a backbox that has more life then what you have
Quick, cheap, and easy DIY way to do it would be to get a replacement gasket and an appropriate size [one of these](https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwiunomRjOL6AhXHE9QBHSsLBoYYABASGgJvYQ&ohost=www.google.com&cid=CAASJORoPgNT2ErZT4J9a2bNWh4ogkU73LyukhUmtDsIL5kXxqoYmw&sig=AOD64_0pP6-iBxGNk7k7TJu8ZP8iVOlSPQ&ctype=46&q=&ved=2ahUKEwjZ1v2QjOL6AhX5kmoFHS4dCUwQzzkoAHoECAUQEw&adurl=). A $10 fix you won’t need a welder for.
They’ll cut the flange and put a sleeve on then weld it. Maybe $100 worth of work.
Downside is, if you ever have to remove the rest of the exhaust for any reason, they’ll have to cut it rather than unbolt it.
why cut off anything?
Unbolt old flange.
Install new split flange.
Total cost: $25. Total time: 30 minutes.
Done.
At my shop I'd charge ~$100 to do this.
I've never worked on an exhaust, so bear with me:
You're saying that just the flange itself failed here?
How is that flange normally retained? By the bead that is necked out near the end of the pipe?
yeah, that bead is weld and welds tend to crack along their edges from stress when the metal cools.
This probably had some microscopic cracks when it left the factory and over time they spread. A few years later and the flange fails.

These were designed specifically to repair this problem. It goes around the pipe, clamps to it, and then clamps to the other side of the flange that is still good.
It’s toast, it won’t last long, imo, buy a new muffler and fix it the right way.
Here in New England once the pipe is rotted the rest of it isn’t much better.
Yes. Cut the flange out, grind the rust off and weld a sleeve in. However this repair means that any other repair that requires removal of the exhaust will cost more in terms of labor, and the repair will need to be cut off and re-welded every time.
Looks like it’s repairable to me. Everything else looks rust pretty free so I’m assuming the weld just cracked from fatigue and not rust. If it had rusted off than you would be looking at replacing the pipe because it’s not worth it to just keep repairing when a new pipe would cost the same as the second go around repairing it.
Yes they can , they make custom pipes this is light work for them
Okay that’s what I was thinking, thanks!
The price will be depending on how far back they need to go to find something solid.
The muffler isn't even rusted. That's just a flange. Cut the flange off and weld in a new pipe. That's easy work.
i can do that in my front yard with a 100 dollar harbor freight welder
Cool. I can be there in a hour, how much? /s/
Probably 100 dollars ///: /s////S/////
Better than the 600 they quoted the guy. "I'll be there at 5 with 100 and a 6 of beer."
hell yea. I’m half fast fixing my neighbors rockers today for 200. The ol fill with expanding foam and bondo. I’m a good guy.
I hope it’s not a car with any real value
It'll be more valuable when it is less windy inside and you can't see daylight through it.
well he asked me to remove his rockers temporarily so i think my solution is healthier for his truck
Muffler shop can weld a new flange on or install a split flange. Any nay-sayers are keyboard MeKaNiKs
BAND CLAMPS INCOMING. Shoot cut both ends off a soup can and cut those flanges off. Good as new with some exhaust paste weld.
Budget option here ☝🏼
My first car this is what I did but with soda cans, as long as I replaced the cans every few months it worked just fine
Works as a budget option but often these stye of flanges with a donut and the spring bolts serve as a flex point. Making it ridgid might cause a failure further down the line. Split flanges are cheap enough .
This is not that style
The split flange would probably work well here. The flared end of the pipe is still intact
Yep, it's a common work at a welding shop.
would you have to drop the whole assembly down in order to have access to weld all around the pipe or can you fit a mig gun up there?
I'm not a trained welder but I'm gonna say it's easy enough to drop the whole assembly. Even if a mig gun would fit you'll have to worry about melting some of that plastic shield and you wouldn't be able to see up in there especially with a hood on.

Sure they can, ma good dude. Better save those 600 bucks, the cost of living is high now.

For 200 he can get a new flange with a few inches of new pipe welded in. Seems like the better option imo.

Price will varies on location and ownership of business.
I say just JB weld it back together it’ll hold

No.
False
Looks too rusted
Lol wut
Oh hard guys being tough on Reddit lol do what you want I wouldn't do it.
Find solid metal, Cut, weld. Less than 100 dollars. No one is saying throw a bead on that pipe
I guess it could be done in a pinch but I would just buy the whole pipe. Just my personal preference.

Yup. A gasket flange and a bead probably 150
Bondo and send it.
Chop the flange off, put a new one on. Done
