Does the M Performance Exhaust for the M135i keep the active flap?

As the title suggests - does the M backbox come with another active flap, does it get rid of it all together or do you pull across the actuator from the standard box?

Those of you who have one - is it just one cut behind the standard box and the M one bolt and welds right on?

Not sure about the M exhaust but I know you can't get the actuator separately from the normal exhaust. They come as a complete package.

The reason I know is that my actuator malfunctioned and BMW have to replace the whole exhaust just because one dodgy bolt in the actuator and flap mechanism.
