This output is specifically designed for RR.
Trying to fit it in an M Performance model, making it heavier than a 4,4 V8 Alpina B7 and with lower performance is not the smartest choice...
Also the price will be higher than the Alpina's..
They choosed to put it next to S65... as super fast autobahn's pigs....
So the real M Performance model is Alpina B7...
