Thread being revived, but has anyone found a way to fully open the exhaust? Just heard my buddies 2023 G80 M3 with the Dahler kit and it sounds more aggressive which I liked.
Assuming our exhaust is the same on all the G8X platforms, this explains it pretty well.
I also found this other valve controller for much cheaper.
