hey everyone, Im looking to put an exhaust on my 04 MZ3 sedan. Apparently theres only an HKS for the Hatch version, which blows because I love the way it sounds. Can I install it on a sedan with minimal problems. If not, what exhaust systems do you recommend for max gains, I live in FL so testing is not an issue, I just want nice sound and good gains. I also like the way the magnaflow sounds, but not so sure on performance. Does/ can any of you awesome people lend me some guidance? Thanks for helping a noob.
