Shits expensive in CA. I know its between $400 and $800 for dual exhaust, depending on what mufflers you get.

My last post of the month!

But i just put a new exhaust on my mazda. 2 1/4" pipe, brand new cat, and a new turbo muffler installed for 160.

anyone have suggestions on a quiet muffler... every where i look it's like "perfermance sound gives you that agressive tone" blah blah blah.... I want one that is quiet
