If you're looking for sound only and don't care about power loss, you can try straight pipes.

In that case, I think RPI makes power. Sounds pretty good. Here is member C's Bimmer M5 shot by member Anthony517

Go with RPi...Depending on how much $$$ you want to drop, they offer alot of hp gaining products...You can get the full race exhaust, pulleys, headers, and oil cooler...
