i might end up goin with them, maybe they make their longtubes better? who knows. i like the pro dumps, the one side is too long and hits the axle when raised with the axle hangin, but thats no biggy, and i think i have their h pipe, it does its job. but the headers give me nothing but leaks. i can tighten them and less then a week later they leak.
did you use better gaskets than what mac gave you? and have you taken the headers off and on ever? any issues with them bein warped and not lining up again?
