I did not have this exhaust combination for very long before adding on the MPE rear section, but I see people asking for clips all the time of the Mid Pipe with ZCP Muffler.
I compiled a few of my iPhone clips and made it into one video. The AA Mid Pipe is probably the best bang for the buck for those who do not like the Natural rasp from BMW's engines.
Mods in video include:
BM3 Stage 1: Level 6 aggression
MSR Intakes
Stock Downpipes
Stock/ZCP Muffler
