I took a stock R33 GTST for a test drive and the guy said it was "quicker" than a lot of them with 3" exhausts, how I took him to mean it was that it was more responsive and had more low down torque, therefore seeming "quicker" if you don't rev the crap out of it. Does the 3" reduce back pressure so much that it affects low down torque? Would a 2.5" be a more suitable choice for a near stocker? I can't seem to find any exhaust FAQs in the search forum, does anyone know where to find some good posts if this topic has been already covered?
At what point of modification does it make the 3" worthwhile (a certain kw, psi, or level of mod?) I want a daily driver that is still responsive down low.
