Re: (91crxturbo)
That's kind of a mixed bag there. With a turbo,, you want as large of an opening as you can get. That why he suggested a 3 inch. The more you close off the exhaust, the more you limit overall ability to "dump" your wasted pressure. See with a N/A system you want back pressure. With forced induction,, you do not.
But, if you are after quiet, i would go 2.25" and a big muffler.

If you have a 2.5" DP, you shouldn't even be considering a 2.25" exhaust.
I would get a 3" exhaust so you have plenty of room for upgrade as you want more power when you upgrade that DP to 3"

Yeah, you are right. I thought about that later after I left the board. whatever the down-pipe diameter is don't go smaller.

Re: (Cookie)
I made over 300whp on a 2.5", turbo style rear muffler and a cat with my stock B16 and it was really quiet...until full boost 
you can deffinatly get away with a more restrictive exhaust if you have open wastegate.
