Re: Warped Exhaust Flanges

What kind of headers do you have? Long tubes? Shorty? 3/4 length? brand? If the flanges are warped at the collector and the pipe... then no gasket will cure that leak unless the flanges are straightened back out.

The flanges you posted above are a stock manifold style with a dount gasket. Not my first choice in sealing anything.

Might just be time for new headers. By the time you pull those out and have a shop charge you "shop rates" for time, you'll probably be in it enough to buy a new set of headers.

Over tightening of fasteners is the #1 cause of leaking headers...
