Sorry, I can't answer your NJ question. But I can say that my catted MRT H-pipe sounds great with the stock cat-back. Can't wait to install my Magnaflow catback....
I currently have the SLP LM 1 w/ the catted Prochamber. Sounds good, but I need louder/deeper. The PC is a very mild sounding mid pipe. Im probably gonna go w/the o/r H.
