Plus, the ess sounds nothing like the mpe, which IMO has a much more unique sound that fits the m3 perfectly.
The ess sounds like just another car and many exhausts sound very similar.
Each option has their unique benefits

I think 15-20hp is a bit optimistic. There is a power gain, however, I have heard more like 8-9hp. BMW does not advertise this, because that kind of power gain is difficult to consistently replicate on a dyno. My guess is that BMW does want to be hit with any kind of potential legal issues if it doesn't show up on a particular person's dyno pull.
