Picked up my new exhaust system for my M3 today. It's called Eisenmann and they do exhaust systems for most German cars.
I got the unit that has 4 83mm stainless tips (stock is 4 53 mm tips). It's the "RACE" unit and is said to give the following:
Performance Level Average %HP Gain Average Flow Restriction
(Stock: 43%) Average Sound Level
(Scale: 10 = loudest, stock average = 2) Average Weight Reduction %
Sport 3.3 - 3.9 % 30.6 - 35.5 % 1.8 - 3.1 25 - 30 %
High 4.1 - 4.7 % 26.1 - 28.8 % 3.3 - 4.7 28 - 37%
Racing 6.1 - 6.4 % 20.2 - 25.5 % 5.1 - 8.9 35 - 70%
Clips can be seen here:

Check out the theater for sound clips.
If anyone is interested in seeing it, I might swing by lafleurs/julep tommorow
