I had an AA system on my old E90 M3 and it was intoxicating and awesome and vowed to go back but after doing more research have decided to go with what, on paper, seems to be what we all SHOULD be after and that is a carefully matched exhaust system that reduces weight, has great sound, and produces more HP!
MFR mid-pipe and Akra exhaust...
