This was by far the EASIEST bolt on exhaust Ive ever done. Its basically idiot proof. Bolts to midpipes, then 4 clamps, and hangs right where the stock system did. Super easy. But the system itself, is not really loud, but def. louder than stock. And I think I like it that way =) Special thanks to Maryland Speed for taking great care of me as a customer too. Ill be coming back!
