Purely a guess, but I am expecting around or just below 400.

Re: Exhaust Diamater

here is what mine currently sounds like with 2.25" and only about 18" of pipe before the muffler. Also on cheap summit headers I have larger chevelle headers to go on when I do the exhaust.

I assume the FM on there currently is a 40 due to the volume.
