W166 Performance Exhaust?
I don't have this option. Since there is no exhaust button how does it work? Is it a valved system? This take-off muffler on eBay says it is the Dynamic Performance Exhaust but I don't see any valve actuators:

Thanks HD. So no valve but I wonder how activation occurs when you put in Sports+? Is it strictly a more opened mechanical exhaust or is it also activated electronically? I guess what I'm getting at if slapping that OEM rear muffler section on is all's needed?
