Hi guys,

I just got a 2016 bmw 435i gran coupe, and I got the optional M exhaust. Whenever I start the car, I have noticed that the passenger side exhaust is the only one open and allows for the exhaust to come out. BMW said the driver side exhaust does not open unless you are in sports or sports plus mode. I looked under the car and I noticed there was a wire going into the exhaust. I wanted to ask if anybody knew how to permanently keep both exhausts open.

I can unplug the wire, but how do I know the valve is open? I look into the exhaust but I notice nothing.

Thanks
