Hi guys.

My car comes w/o muffler switch on the center box. (only 1 button is placed there which is ESC off?)
Anyway, If I can buy only a set of buttons, Can i activate that function?

As I guess, when I put into Dynamic mode, valves open and sounds changes.
meaning it have active exhaust.
Have anyone tried this?

 

Don't think it has active exhaust, but is louder than closed version on active exhaust.

 

I've never really seen the point of the switch - if you want the valves open all the time, select dynamic mode, if you want it quiet, dynamic mode off. You can't do anything about the valves opening after around 3,500 rpm. In my MY18 switch the valves open in non-dynamic mode causes them to open at 1500 rpm, so quieter at tickover than in dynamic mode.
