I find these cars come with decent power already but they are missing the emotional pull that comes from a more involving exhaust note. For the m550 in particular, an exhaust isn't going to add much power but just a little more burble off idle at a bit more noise in general would make the the experience feel MUCH more special. I would put the quality of the sound above any of the other considerations!
