Drivetrain Bi-Modal Exhaust for R56
I have this on on my R60 that also had a Magnaflow exhaust. Works great when I want some extra rumble. It takes about 8 seconds to fully open and close.

Yes I used a QTP too.
The valve itself doesn't mean much, it's the exhaust design that matters.
The valve open a secondary route that is usually shortar and/or more direct than the "quiet one".
What i got on mine is one straight pipe route, 65mm, which opens up when the valve open, and a silenced one, still 65mm.
