Default True Duals: 2.5" or 3"?

Hey guys i'm doing a true dual system on my car now dumped before the axle. I was going to go with the Magnaflow 4x9 but i'm debating rather to run full 3", 2.5" or 3" into X-pipe and 2.5" out... I'm not planning on doing anything more than a cam and MAYBE some nitrous. What do you think?

Dr Gas has oval 3" that is 2.5", they have the whole x kit in 3" oval. And adapters to round. Kind of pricey, but depends on what you want. drgas.com

3" is much louder than 2.5" I would choose the pipe on how loud you want your setup. I had 2.5 duals with 1 chambers on my WS6 and it was loud, on my firehawk i went with 3" 1 chambers and its too F'n loud!
