You are right the way BMW uses their CCM(Cylinder-bank Comprehensive Manifold) with the twin scroll turbocharger is to keep the pulses separate. What I was suggesting was not to use the CCM and apply another technology to take advantage of a 6 cylinder engine combined with two twin-scroll turbochargers. I can think of two potentially effective ways to do this and I am sure BMW can think of many more. Of course they may do something completely different, I was just speculating
