lol yeah the duals are nice. but the singles always give more power... i got a 60mm which isn't the best.. but the duals are just eh. i <3 the look of a single... i'm getting the rear exhaust cover that covers up the other cut out.

and i was looking @ a fujitusubo and Comptech set of duals... but neither gave anything more than like a 2 db over stock sound... and maybe like 4 hp... if that... it wasn't worth the 1000 plus for a good dual when i got this apex for 400 bucks under MSRP and got more power... plus its got a good WOT/VTEC sound and no side affects on the normal driving interior cabin noise
