i am planning on putting on exhaust saturday and i was think about get 3in or 3.5in exhaust pipe but is there a difference between the two or 2.5in. im putting on a super 40 on a nnbs 6.0L and i was wondering if there would be a big difference in the size i use? thanks

Single 3in. should be best for your 6.0. Had seen a guy with a 6.0 running a single 3.5in. into a Borla muffler. Duals: 2.5in. piping.
