I have a full de-catted setup with the factory stock exhaust flapper solenoid.
Normal operation in comfort mode, fully open with burbles in sport/sport+.
I have never done an exhaust upgrade on any of my BMWs that i have owned. Only ever done intake and suspension. I will be getting this brand for every BMW I own moving forward.
