Just seeing if anyone knows the stock exhaust size on a NBS of the top of their head, its a little late to go out and measure mine.

The y-pipe is 2.5 and after the cat/muffler joint, it becomes a 3 inch diameter as it goes into the muffler. I believe after the muffler it gets reduced back to the 2.5 inch size. I am not 100% on the after muffler size, but the other parts I am certain of.

the stock pipe on my 04 is 2.75 in/out of the the muffler.
