The 2015 550 certainly does not have an exhaust synthesizer. Unless it is a synthesizer piping the sound of crickets. The 550 has absolutely no exhaust note.

The M5's have a nicely synthesized exhaust note that runs into the cabin. The M5 also sounds decent outside the car.

The 528's appear to have the sound of a 1994 Chevrolet Cavalier; that sound being the clanking from the engine itself.

It appears the best sound available on the F/10 (sans the M5, of course), is a 535 with the M Performance Exhaust. That is a nice sound.

The sound synthesizer doesn't transmit exhaust sound. It's the intake/engine sound that is synthesized into the cabin. It's also not a microphone picking up the real sound but a digitalized pre recorded sound track that is channeled through the speakers.
