so ive replaced the two gaskets after the manifold before the cat twice in the last few months. For some reason they just wont seal tight. ive cleaned the surface good, used good new exhaust hardware and even used some muffler cement on the gaskets the second time around. Has anyone else ran into this? because im gettin ready to just buy a full exhaust system......not that i dont want to, but i dont wanna break into my streetbike fund lol
