Just installed a pair of NPP mufflers on my 12 SS. Thanks Nick151LE !

I have only started it in the garage as I still need to get them fully welded up, just tacked for the moment. All I can say is wow. I am mildly cammed but cold start, the car sounds really pissed off. For years I have heard people saying that it is one of the best sounding mufflers out there when paired with long tube headers. I think I am probably going to agree.

Bolt on I assume? What size are they 2.5? Also, how did hook up the valves? Are they vacuum or electric?
