Okay I'm buying a used BMW e46 330i (preferably with sport package) in the next two months and wondering which exhaust system would provide my car with the best exhaust note and performance .My budget is around $1200 and I favor clean, deep racecar tones, not the raspy, obnoxious ricer tones (if that makes sense). I live in San Diego and I'm not familiar at all with the cities emissions laws, but I probably need a system with catalytic converters (maybe high flow cats) and I'm not sure if resonators are needed. If anyone has had experience with BMW exhaust systems your response would be greatly appreciated. 
Some of the systems i have been looking at are: eisenman, remus, borla, AA, Supersprint, DINAN, and Rogue Engineering.
Thanks for your time!!
