I don't have my car yet but I got the exhaust.
I got the GMPP STREET version. Just thought I'd share my thoughts on it real quick.
The mufflers are small and nothing tricky inside, It's almost a straight shot all the way thru. There is a very slight curve inside the muffler, no baffles or anything like that. It's just perforated all the way thru. My take is that is the same as the offroad version with a bigger can to hold more sound deadening material. Welds are nice..
