There were a few posts asking if the msport still had this valve assembly and had not seen a definite answer so I went out and looked. '11 550 msport here, I do have a valve that covers the inside exhaust exit on each side. I did as others here have done with removing the drivers side trunk liner and bypassing the black switch. The valves are now both open and the sound is deeper, haven't had a chance to drive much but will report back if drone or other issues come up.

Edit- just noticed this is in the E60 forum, so disregard the above!
