Reading all the posts on G87 M2 exhaust (s) is downright exhausting (pun intended).
My new 2025 M2 has me confused, can't get a handle on real engine noise and how to control it vs ASD which I want to avoid.
In my M1 and M2 buttons I have turned off ASD but is there a flap operated exhaust system that activates under certain settings?
Do the drive modes activate ASD in some amount?
I've trolled the forum and google but cannot find a good explanation of the overall system, is there something out there?
all repossess welcomed.

Full disclosure: I don't own an M2 yet

From what I understand, there is an exhaust flap but it is never fully open (even in sport settings). That's why people here get a valve controller to fully open the exhaust flaps.
