The diameter on the exhaust I have is 2.5" dual. I believe it's the same for stock and most other aftermarket systems. Enjoy the cutouts :D

B&B Tri Flow = 3"
Power Effects = 2.75"
Borla = 2.5"
Corsa = 2.5"

It's 2.75". Interestingly, the inlets to the stock LT1 mufflers are 2.5" - the pipe necks down just before it's welded to the muffler.
