Even better go back to the E90 series...which the V8 sounds hard and solid every time you apply throttle.

The S55 ZCP sounds better than the standard S55 is because of the tune rather than the MPE. The muffler is there is to filter sound but can't add sound if the engine is not producing it. So no V8 or V10 or V12 sound is available with any exhaust system placed on the S55 or N55.

The S55 M2 CS has the potential to sound even better than the M4 ZCP with MPE if they get the tune right. I am sure having the right balance of 'appropriate sound' both from inside the cabin and from outside is one of the engineering objective that they have to tick off on.
S55 sounds inferior, mainly due to its twin turbo setup acting as two mufflers, so does N54. ZCP adds a few burbles at middle and lower rpm ranges that's appealing to untrained ears but at high up it still sounds like a broken can rubbing ground. They are basically two turbocharged 3-cylinders working together, which is why you rarely find a L6/V6 twin turbo engine in the market sounding good. Zero chance M2 CS will get away with that using S55.
