hey man its doug, you shouldnt have any problems, mines lowered 2.5 inchs with the bassani. just take it easy crossin speed bumps and all. as far as sound, like i said mine sounds like a cobra with the loud mouth cat back. but ive gotten nothin but complaments. but ive heard way louder, now that i thought about it my buddy has has the pypes-x and i think hes runnin the same flows as min and yours, so i know you wont have any problems. as far as install, not a problem either, just make sure you have jacks, and jackstands. and some pb blaster to spray on you bolts about 30 mins. prior to workin on it, and power tools are nice for the manifold collector bolts, but hand tools will work.
