I am not that knowledgable about Audis but always wanted one.. I am coming from a 350z to a 350 whp Sti to making a decision between a S4 or S60R anyways.. I have become fond of turbo charged cars (s60R) and I know the b5 s4's are but I don't like the styling as much as the newer ones . So being that it's N/A how much Hp can u gain from a Miltek exhaust, or chip from this car? Being that's it a V8 and already has 340 Hp I am not sure if u can really get any more hp from it or am I wrong? I know the older S4's (turbod) have a chip that gives u like 40-50 hp that's awesome and the s60R has a ecu upgrade that gives 54 Hp aswell..
Thanks
