2019 S63 COUPE
Exhaust flap
I had 2017 s63 and 550 coupe and could see the flaps on the rear exhaust that changed sound in different modes.
I had my 2017 sl 550 on the ramp today and there are no wires or vacuum lines going anywhere on the exhaust system.
I can only assume that there is something going on at the manifold with the turbos to change sound in sport modes?
anybody have any ideas?
