I think it opens under acceleration. I seem to recall that a little back pressure is good up to a point. It is not intended to make your car sound like a race car because your car is not a race car.

Electronic cut off valve

Hey Alex. I think this is what your looking for:

You can reach of to the vendor and see if it’ll fit your W222.

Good luck, I’ll be nice if one can control the opening and closing of the exhaust cut off valves.

thank you for looking at this, although i wanted to see if u can disconnect something to keep these open, (like on the 911 pse system) itsi not gonna sound race car obviously, but it gives off a slight rumble like a s63 without all the craziness

I have the S63 and love the sound of the rumble, but if you are looking to get more exhaust note, the electronic cut off valve is the way to go. There is nothing you can turn off or on to make stock valve stay open.
