I had a Supersprint exhaust installed on my '97 ///M3 Coupe and the sound is significantly louder (and better) especially as rpm's increase. I really like the new sound. I did have a little problem with the exhaust shifting after installation and causing a "thumping sound" when going over bumps. I had to have the installer redo the mounting. He said the mounting system for Supersprint is a little different than the staock BMW mounting and that's what caused the problem. It appears to be corrected now. Good luck.
