I own a '99 audi a4, which amazingly only has 120000 miles on it after 10 years. anyway, since its a british car the steering wheel is on the right side, not like this has anything to do with what i need help with. I was driving around the other day and suddenly my car started to sound like a harley rumbling down the road. When I got back home I looked under the car to see what was wrong. Right where the header comes off the engine and connects to the cadillac converter there was a clean sever in my pipe. By the looks of it, it suggested that there was some kind of mechanical bond holding the two parts of the pipe together and it had fallen off. Now for the question. Would it be wiser to have the two halves welded together or just find the part that was holding them together in the first part and replace that? Right now I'm looking for quick fix ideas that I could do just to make it less noisy, and remember this is coming right off the header so the pipes get extremely hot. I was going to try getting some pipe tape, but my local station here doesn't have any.
