I just installed my magnaflow catback and I seem to have stripped one of the bolts that connects the extension pipe to the exhaust manifold. I took it to a shop to have the pipes welded where the clamps are suppose to be and have the pipes raised. I told the guy that it rattles everytime I hit the gas or go over a bump and he said its because that bolt its stripped and is not holding the pipes tgether as tight as it should. Now I just went outside and start my car, I redlined the crap out of her a few times and it didn't make any rattles at all. Can anybody help me before I get under my car and put a new bolt in and find out its not the bolt?

Well I got under my car and I think I know whats wrong. The extended downpipe is touching what I think is the control arm? All I know its touching that bar and I'm guessing thats what is causing all the crazy rattling, I'm going back to the shop to have it fixed, hopefully thats what the problem is.
