The courtesy pipe falls right inbetween 21/4 & 21/2. It's metric so I'm not
sure either. I just know it's larger than 21/4 & smaller than 21/2.

Remember I'm running 21/2 cat back to a 21/2 straight through magflo
muffler.
I ran a 14.7 @ 94 mph down at Capitol with this exhaust. Remember also Alex
that was with the # from the Rosen dyno :-( So I wouldn't say that you lose
all
that much on bottom and you gain quite a bit up top. Will a B14 exhaust fit
under your NX? If so you can have my exhaust in a week or so,
I'm going 3 inch :-)  Joel
