I've been complaining a bit that my S50 with Vibrant mufflers was too loud. I swore up and down that it had an exhaust leak but could never find one. Well tonight I got so aggravated with it, I decided to pull my headers out and look as it was driving my crazy. I found this on the top part of the exhaust, next to the floorpan. I ended up pulling the headers and all of the exhaust off. Most of the welds are crappy, I'm taking it back up there in pieces so they can weld it back up properly. The flanges were welded on but not flush to the ends of tubing so there weren't any flush seals at the flanges?!?!?! So I took the grinder to each flange and ground each one down so the gasket will actually seal. What a crock!!!!

That doesn't look like they used stainless MIG wire, either. If you had any stainless, it's effectively ruined. Nice hack job.2006 GMC Sierra 2500HD 4WD LBZ/Allison

Any mechanic or automotive related tech does not like you right there watching over them, TRUST ME.

It must be something with exhaust shops in the Carolinas because my cat delete pipe looked similar. They didn't even take the exhaust off the car..... They were trying to weld around the top with the car on a lift, them standing on a cinder block and peeking between pipe and floor pan to attempt to get a good seal. And then they had me jump in the car, turn it on, they felt for leaks and proceded to weld where they felt air coming out. Afterwards they told me if it still had a leak. To use JB weld. WTF? :down:
