I put the SLP 1 5/8" headers on my car and I can't get the passenger side collector to seal properly, I used the gaskets that came with the install kit, tried to reaplce them with the Fel-Pro gaskets that are listed as an alternative in the article about alternatives to the install kit, they didn't fit at all. I had to goto an exhaust shop to find another set of gaskets to throw in there but it still leaks, any ideas? Thanks.

 

Try aluminum gaskets they usually seal even with warped flanges.

 

Cool thanks!

 

I had the same problem, I am goin for a month now with double stacked fel-pros with not even a whisper of a leak, We'll see how it does, Before it leaked enought to roast a new gasket in 2 days
