E92 M3 Sound!!! Eisenman Race + Supersprint?

[tomvcarter]

I just had an Eisenmann Race exhaust fitted to my M3, it is amazing. Not too loud as many people said, but im now wondering what else can be done to the exhaust to enhance it more so.
What benefits does adding something like a Supersprint X-pipe or similar have? and does anyone have any suggestions of what else i can install to enhance it...more, or would i just be wasting my money?
What is the best sounding combination?

Do you want just noise? I bet from the outside it is a lot louder than you think. You could put some racing cats on there, that makes it louder.

No not louder, just wondering what the SS Xpipe or similar does. Is it just improved airflow, therefore slight power increase, or is there enhancement to the sound as well? What are Race cats?
