ive decided that im happy with the ride of my stock 20's and im going to keep them that way (yeah right!) but this car needs a nice rumble. i heard a RR sport sc today and it sounded mean, really mean. lets hope someone comes out with one. maybe supersprint or one of the mbz tuners will come out with a system. i dont want to settle with a magnaflow or borla standard muffler. although they sound great on american suvs. hurry up and wait.
