As far as fit and finish goes...it is excellent. I had zero issues during the installation. If this is a street car you need to know that this exhaust does not work with OE cats. The installation is not bad at all provided you have accounted for the need for a rear diffuser, or a heavily modified rear bumper cover. This exhaust will not work with a stock rear bumper cover. I am running Billy Boat headers as sold originally by RM racing. I had to wait 3-4 months for my exhaust to be built, but I think Chris at SOS can get them faster from time to time.
