This motor uses a bi-scroll- that is the whole point of this motor.
A twin scroll or bi-scroll essentially is two turbos in one as they can effectively stream the exhaust to the vanes from alternating cylinders and not cause turbulence.
The new ///M motor started the BMW twin scroll reign, with this following suit- there are more on the way.
