Drive in D5 mode... The rpms stay within the exhaust's noise cancelling chamber range 90% of the time.

If you want an american V8 sound, AA is not for you. The AA is a smooth, refined German tone with a little exotic sound mixed into there. It's not quiet, but it's not "Hey, look at me, I'm the stereotypical M3 driver needing attention". It will turn car guys/girls' heads because they want to see where that refined sound is coming from. It's classy enough I can drive it to work or a professional event and not be embarrassed. Fits the M3 well, classy... yet the wide fenders and the power bulge covering the ITB tell you there is something more under there.

Of course, this is my opinion. Best bet is to listen to the exhaust live by meeting people local to you. I bet the next poster will be someone bashing the AA exhaust
