Well just spent the last few hours doing the exhaust mod that every one has been doing. Well power wise it seems to help but i hate the sound. Idle isnt bad but up in the higher RPM's it sounds horrible. like a cherp type whistle sound. Ohwell i guess i will just have to put up with it til i get an aftermarket one. Not that its a bad idea because it does make quite a power increase just sound very good. The low RPM rumble is pretty sweet though.
