exhaust leak

TJR · 06-08-2002, 08:01 PM

I just got a mac o/r H-pipe and I can't get it to stop leaking at the flange where the headers (mac 1 5/8" unequal shorty) connect to the H-pipe. It also leaks at the cross over tube a little bit. Do you guys have any suggestions?

weld a piece of sheet metal over it;-). just kidding. you might have to take it apart and put it back together. when you do that, make sure everything is sealed tight beforeyou put the next piece back on. if you have the means, weld it. it'll hold a lot better than those stupid clamps.

I used a little of that muffler paste stuff between the h-pipe and my BBK shorties. It did the trick, I couldn't get them to seal without it.
