If you're serious about the performance and don't mind the extra cost, then full-race is the way to go.
If you want the best bang for your buck and mainly want a loud exhaust with some power, then the rv6 and tsudo[/quotIs
Not sure how much, but rv6 is a 2.5" dp abs the tsudo is 70mm. Full race is full 3"
Is the full race to loud? i was thinking about getting the invidia q300 but i heard it was to quiet so i was thinking about the N1 but i was now debating between the N1 and the full race. Do you know if the full race has alot of cabin drone? i want something id be able to hear with the windows up but not so loud where i have to yell on the highway
