Is that the UUC RSC36? Is it really drone free?
If I use too much throttle below 2k rpms my entire cabin is filled with something that sounds like a skrillex song frozen on the drop. Sh1t's ridiculous. I sort of want to swap it out, but then again I haven't seen any other person with a B&B tri-flow on an E36, and it does sound like angel porn under full throttle.
The only other one that really gets me going is the eisenmann race. God that exhaust sounds insane. Then again, not popping my ear drums out when I'm lugging around in traffic might be nice too...
