I'd like some advice on exhaust systems for my E92 M3. I've listened to as many sound clips as I could find (trying to get to hear these in person, but no luck so far), and would love some real world experience input. I love the deep growl and burble of V8s and have always felt the M3's exhaust note was rather muted and pitched a bit to high for my liking. For those of you with experience on the following exhaust systems:
Eisenmann race
Mistershaft GT2
Gintani
Akrapovic Evo

Could you rank them by:
1) Deepness and richness of tone, greatest to least
2) Loudness, loudest to quietest
3) Livability as a daily driver, easiest to Tylenol needed

Looking forward to learning from all of your experiences!
