I’m going to verify by pulling the fuse, but I really wish flaps were a simple on/off ordeal. Makes me hesitant to get aftermarket axle-back solutions, as this sound / behavior still may exist.
Did you end up pulling the fuse and having it paired with the eisenmann midpipe? If so, how was it? Any terrible drone?
