My stock exhaust is long gone but I’m pretty sure I recall measuring and it’s not 3”. Yes I believe the input and output from the muffler is, but the rest was something like 2.6” with some even smaller parts in a couple places.
The od of the tail pipe is 2 15/16's". The replacement pipe where the muffler used to live was 3 inches. The exhaust was necked DOWN on the intake side of the stock muffler,and then necked back UP to approx 3 "s.
