LOL, the GReddy Evo and HKS exhaust are the quietest muffler-tip style exhaust, then its Borla, Magnaflow, TRD
, and TPR.
I love my exhaust (apexi n1). i love the way it sounds from inside the cabin. when i let my friend drive my car once, i heard my exhaust from a different point of view and God is it so sexy.
nothing ricey at all. gains are good and the sound is at a great level, though i have gotten 2 tickets for it.
[b] the apexi n1 exhaust can fit both the GT and GTS, although its labeled for only the GTS, it will fit. i heard that there really isnt any difference btwn the axle-back exhausts for the gt and gts.
