Anyone have the Corsa cat-back?

I bought my 07' this week and it already has the Corsa axle-back on it, which I know is like $650 It does sound good, no drone at all. I'm just used to the way my 5.0 sounded. I'm having a lot of trouble deciding on what mid-pipe sounds best with these mufflers. Any opinions? I listened to the few sounds clips in the sticky, but they all seem to sound very raspy. I want it to sound clean with no trumpeting. I'm on the fence on catted or not, as I do have to worry about emissions, but have a friend with a lift that I can thrown the stock H-pipe back on to pass the test. Please chime in with opinions, or sound-clips that I haven't been able to find, thanks!!

*BUMP*

So what I'm looking for now is a sound clip of an O/R Prochamber and Corsa axleback. I can't find one online anywhere? Please help!!!
