Myth33

Thx for the advice 'rob' and 'elithrar'. Its comforting when different people can agree on the same things . So Apexi cat back with a hi-flow cat seems like the way to go. So I'm assuming the 3"dump pipe makes very little difference then, or not as much as Hi-flow cat plus a good cat back system? As far as the noise is concerned is it very loud? I mean street legal?

Hi all, this is my first post here. I've finally ditched my turbo VL commodre and bought a 94 R33 GTS25t (auto). I really want to do just one or two little mods on my car and was wondering where would be the best place to start. I was thinking about a full 3" Mandrel bent exhaust with dump pipe, hi flow cat etc. I have been quoted $1200 from an exhaust place, is this a good place to start? And I also would like to know the difference between Stainless steel exhausts and regular bent steel ones? Can anyone tell me the noise difference. Also should the car be dyno'd or re-tuned in any other way if I do this mod, because I don't want to have ruff idling etc. (Reliability is important to me) thx in advance
