Bought a used Tsudo catback exhaust for my 98 hatch. My question is do I have to use the metallic flange gaskets? I already have the hi-temp exhaust gaskets, but they are the paper-like ones. Oh, and I'm building a turbo kit, so I have a turbo manifold and not a header to bolt the catback to. Will the catback bolt up to my stock manifold without any problems? (catback is 2.50") Thanks guys.

 

bump?
