Install:We started at 10pm and finished at 11pm from the time we loosened the first bolt on the stock exhaust until the last bolt on the Ark exhaust was tightened. The install was pretty straight forward and the build quality was very good. I have to readjust some of the bolts since the driver side tip was sticking out more than the other but I believe that was due to our fault installing at such a fast pace. There were no clearance issues with the center brace like the Stillen exhaust. The exhaust comes in 4 pieces with all new hardware and gaskets. Looks: I've never been a fan of the burnt tips but I must say they look good. The exhaust does hang a little lower than the stock one but not by much. It looks great looking at it from the rear. Sound: Well since sound is relative I'll give you my opinion. Good:The gurgle on deceleration is awesome. WOT sounds like a it just wants to eat you alive. I scared a couple of people just cruising by and downshifting with SRM lol!
