i got a 95 R33 GTST, and i hav e been told first thing to do to a stock car when doing it up is the exhaust, its always a starting ppoint, so what exhaust should i get, ev eryone has said 3" madrel bent cat back, but whats all the 'dump pipes' and stuff about ? i want the BEST performance and i dont want it loud, i only just wanna hear it from the cabin, but outside the car it sounds just nice, im sick of my 'hey look at me' exhaust on my last car which probably decreased performance LOL!
