CONGRATULATIONs on a successful install and the fact you are very happy with the added sound noises. Did you have to remove the rear lower fascia in order to install the x-pipe to the existing muffler/NPP system? Can you still operate the NPP valves in order to silent the exhaust?
You keep asking questions, did you check with your dealer about voiding warranty and post us their comments?

i only replaced the X-Pipe which is located between the stock NPP mufflers and the flange at the back of the headers. The main cats stay in place and the rear pup cats are welded to the stock mid pipes. You just remove the skid plate, disconnect the mid pipes just forward of the pup cats, loosen the clamp at the rear of the mid pipes under the transmission, remove the rubber damper and the stock mid pipes dang near fall off. Then you reverse the order to install the new X-Pipe (don’t forget the donut gaskets) and it’s done. The NPP valves still work the same as they did with stock mid pipes. No need to remove the rear facia. Good luck!!

Installed the AWE xpipe last week and all i can say is Wow, the car really sounds awesome in sports mode when you step on it and sounds same when you are crusiing in touring mode , i feel its revs smoother and car feels faster, not really sure if its really fast but feels like that
Special thanks to devnull who installed it in his garage, he is such a nice person and installed like a pro in 45 mins while i watched him in awe. Thanks buddy.
