Default Does Size Matter?

There have been some great posts concerning aftermarket exhaust systems and Magnaflow is the one I am considering. I have a single exhaust Hemi so it seems I will need a single in- dual out muffler but I have a question. Does the outlet size effect performance? Does a 2" perform differently than the 2.5 or 3" outlet? Is torque due to back pressure effected? I realize I am being a bit anal but I want to get it right.

An average cat an muffler create 1-2 psi of back pressure. The smaller diameter will create more back pressure. Your motor needs a little bit of back pressure, what you'd get with a 3" in 3" out will be plenty
