I am glad I bought this exhaust. The only issue I had was that the tapped threads for the b-pipe to back pipe wasn't big enough for the included bolts. The best way to solve this is use a 5/16 x 18 tap bit and a set of 5/16 x 18 x 1 1/2 bolts and nuts. Other than that it installed easily. It has a nice rumble but not like a fart can that I see on a lot of tuner cars, and when you get on it is nice and loud. Great power improvement when adding an aftermarket header, downpipe, and tune.
