Thanks. I'm ok with it being loud outside, as long as it's not obnoxious or "gets everyone's attention" loud. That being said, I'm thinking the ACM mod might be a good fit for me, although I still haven't heard one in-person.
To other E93 M3 owners with the ACM mod, can anyone confirm whether the sound with the windows and roof up is similar to his video starting at 1:20?
It sounds fantastic to me with the windows up (of course it's hard to know exactly how loud it is from watching a video) but I believe this is not the ACM mod but something similar done by another Board Member a while ago.
Thanks for everyone's help,
