Muffler question

So I'm in the market for some new mufflers. I currently have 2 1/2" pipe going back to the 3" 10 series flowmasters but way to tinny sounding for me. So I'm thinking I might try the hooker aero chamber muffler. But my question is: is there any kind of sound difference if I was going to get a 3-3 1/2" muffler rather than the 2 1/2"? I want it to sound deep and loud but still clean and choppy. I didn't know if the 3 1/2 would just sound drowny sounding. Thanks for any help. -kory
