After 4 months of hibernation and installing a catless Borla x-pipe during the "sleep", I decided to start my car as it was a fairly warm day yesterday. I was a little hesitant because of the potential noise from the x-pipe. I also have ARH mid length headers, a Halltech carbon cai and B & B Bullet exhaust with the NPP valves and actuators deleted. I have read numerous threads where the new x-pipe produces a louder exhaust. I pushed the button and a wonderful symphony of engine muscle gurgled out. The initial start was a bit of a bark, but the car soon settled into a nice low growl. Actually, it sounds much better with the new x-pipe then with the stock x-pipe with the cats. Another month of sleeping then it's fun time.
