I just returned today from magnaflow exhaust, after responding to the free exhaust post. I drove down for a cat back sytem fitment for the mp3 and drove away 30 min later with a new exhaust. They said that i could expect a 6 to 10 hp gain at the wheels. So just to let all you out there that want an aftermarket exhaust that is good, it will be coming out in about 2 months or so.(they said)but anyways i like it it has a really nice deep sound that that stock racingbeat exhaust doesn't have. i will have pics soon too.
