Battle For The Best Exhaust:

Competetors:

1. AC Schnitzer (Currently Installed)
2. Radenergie
3. Supersprint

I have an 05 Competition M3 Coupe. Right know I am leaning toward the Supersprint setup but then I found the Radenergie exhaust. I heard the Radenergie was REALLY loud. If anyone has any thoughts/ideas please post. Pictures or sound clips would also be great. Thanks for your help guys.
