I'll give another vote for 2.5". You will probably lose some lowend torque with the straight pipes but when you do the h/c/i swap you'll be ok.

torque down low is what gets you off the line

with a bigger exhaust you lose abit of the low end torque for HP up in the higher RPMs

stock is 2.25
any aftermarket exhaust you find is going to be 2.5 or bigger, but always noted.
2.5 is perfect for under 500hp. anything above that and you might wanna step it up.
