2.5" or 2.25" tailpipes for dual exhaust?

[freddye13]

I have decided on a new exhaust for my 2008 5.7l tundra. I am replacing it with a Borla#40670 2-2.25in 1-3out, then a aeroturbine ar-25, then a Y pipe, then duals the rest of the way. But i am not sure which size to go with the duals, 2.5" or 2.25"? I am mostly intrested in low to mid-range power, a little louder with hopefully no drone. Any Comments?????
