The Sport system is not numerically louder, just much deeper and better sounding than the OEM system. It's perfect for those who want a better sound, without extra sound volume.
I can vouch for the fact that regardless of what the numbers say, the Eisenmann Sport produces a much more satisfying sound than stock, that also seems somewhat louder.
