Here is a clip of the active autowerke exhaust. This was taken using a camera phone by one of Active's employees.
I personally really like it; it's just the right amount of aggressiveness for me, especially on a car making over 500 HP stock.
Please note this is the full exhaust, including AA catted downpipes. If it's too aggressive for you, you can keep the downpipe stock and only get the midpipe and axle-back. It will tone it down significantly
you can also keep the midpipe stock and only get the active axle back for an even quieter sound
