I think if there is a problem with the exhaust, it's so purposeful sounding and unobnoxious that we can't tell anything at WOT. I've seen decibel meter tests and IT IS LOUDER than OEM in the higher RPM's. For whatever reason it's just not constantly in your face with it.
sycd, I have the Race. The Sport is too quiet IMO.
