My collectors are warped. They meet at the three points of the "triangle" but the metal between leaves a rather large gap where i have a very annoying exhaust leak. I have tried doubling and even tripeling the gaskets on them but it is still not enough. Do you have any suggestions? Is there a product out there that goes inside the the header and the exhaust pipe that bridges the two? I don't know if it matters but i have a 69 firebird and three inch collectors. thanks for your help.

Jeg's & Summit's catalog list new flanges,(cheep) get a new pair weld them on for a leak free fix.

You should fix that exhaust leak as soon as you can, unless you don't drive the car much. Exhaust leaks can be really bad for your health.

also jegs,summit and most parts houses sell a collector gasket(alumaseal is the brand i have) made of dead soft aluminum i have used these on my own headers to block and the collector with great success warped or not they form to the surface and usualy you dont have to retighten them like regular paper gaskets

I had a gto once ,, I had headders that leaked , after much aggravation my friend at the muffler shop made me a set of adaptors and we cut the flanges off the headders and welded them solid . The argument is , well If I need to take the headder off Im screwed , my argument is if the exhaust is right you shouldn't have to take the headder off , even if you need to replace the starter ,, and on a pontiac , it helps to loosen the headder , having the pipes welded solid still doesn't matter . If you have ceramic headders .. buy the long 12 inch heavy collectors from summitt

have them welded it will end the problem for good

another suggestion steel exhaust doughnuts the same type that go into a standard exhaust manifold and head pipe set up
