best exhaust setup while staying perfectly smog legal..

[czstang1701]

Ive heard, i guess just dumb rumors are all they are, but that MAC doesn't make very good headers. Then again alot of people i know have them, so that must be a dumb rumor.


Should i stick with an h-pipe over the x-pipe? THe h-pipe gives a much better sound at lower rpm's...or so ive been reading..as the x-pipe gives it at higher rpms?.. When i change my exhaust out, im going to change alot of it at the same time, to make it easier.


And with warranty issues, they can only void the warranty on my exhaust system right? Not the whole car? Thanks for all yer help.
