Stock diameter is 2.75 inches.
You will have to get a 3" cutout since they only make them in 2.5" and 3.0" sizes.
I would reccomend the Zed style cutout also.

I don't know the exact size right off the headers before the y-pipe. I'd guess it's 2-2.5" in diameter. The I-pipe, from the y-pipe back to the muffler, should be 2.75".
