I have a 01 330Ci and i want to know what the best exhaust is for my car and i want it to be a alot louder than most 330ci's. Please help me out and sound clips would be very helpful.

I would highly recommend purchasing the Eisenmann Race exhaust that is available for your car. Great exhaust that'll definetly improve the sound quality of your ride. :)

If you'd like any information, please let me know.

I think the guys in the E46 section(non-M) can help you better, although many in here have had 330's at some point. I have heard Remus is pretty deep and loud on the 330's compared to the M3's
