MRED355,
I don't think that I can be much help on this subject because I have the ATR Pitbull 2.5" SS Dual Exhaust on mine.
I think that it is nice and mellow at idle and just cruising around, but when you hammer it, and the turbo comes on it sounds like a pissed off chainsaw!
I'm not sure if there are other mufflers out there that can sound even more aggressive than those.
The little V6 has a kind of toned-down exhaust sound to begin with, then you add the Turbo to it, and it drowns it down even more.
You actually may be happier with no mufflers and straight through 2.5 or 3 inch pipes out the back?
Remove the ATR Mufflers and fit in some straight tubing and give it a shot, since those mufflers are a 2.5 inch center in, center out configuration.
Good Luck and ENJOY!!!
