Exhaust question.

[240sxHitman]

FIRST OFF THIS IS NOT A TOPIC ON WHAT EXHAUST IS BETTER TO GET!

ok, I just recieved a high flow cat and no gaskets, but i have a 3" HKS hi powered exhast that has one gasket to connect to the cat. I just need one for my stock headers to my high flow cat. now the question is can i use high temp copper sealant to put on it? or would a place like autozone have the same gasket to match the flanges i have

yeah any parts store should have a 3" metal exhaust gasket, make sure you get a metal one though and not the paper kind, that close to the engine will burn up the paper kind, i know from experience. oh and you shouldnt need any rtv or anything, just the gasket

Copper is the best way to go. I would even suggest replacing the gasket that mates the header to the gasket with a copper one if you haven't already done so!

thats for the info, and one more question the hi flow cat is 3" will that be able to fit the stock header properly?
