Muffler Inlet...2.5" or 3"?

I'm looking at buying an aerochamber muffler, SI/DO, but it only comes in a 2.5" inlet. Are there any drawbacks of going with a 2.5" inlet, instead of 3"? Any help is appreciated! This is for an '05 5.3.

Would a single 3" outlet sound deeper?

Will dumping the aero create a lot of in-cab resonance? I was thinking of dumping it just before the rear axle.
