got a b18c in an eg, have a header question, this actually may pertain to any header, but the megan one is what i'm interested in, particularly the one with the 2.5" collecter, I have megan exhaust and a megan test pipe, my question is, how will the 2.5" collecter bolt up correctly to the "high flow cat"(its a actually a resonated test pipe) when its made for a 2" collecter? does that work? and wouldn't i have to buy a different donut gasket, if so does the megan header come with that gasket, if not where would i get it. oh yeah, and i searched, so don't even try it lol, thanks in advance guys

 

no ur gonna need a new cat or test pipe that has a 2.5 collector donut gaskets can be found at like autozone and such places

 

where can i get one of those?

 

try kteller.com they have good stuff
