so he wants the fastest exhaust, with no noise? lol.
you can only have one or the other (usually)
ok this is what you want. Obveously you'r chasing power by looking at your setup, so obveously 3.5 or 4 inch is the go, or you can splurge on a twin system which is pretty much going to cost double. resonators (hotdogs) decrease drone, everyone should have one. baffled mufflers are going to slow you down, so go the big sports ones, and just get 2 of them. this should be a pretty quiet.
