Mine is Sport too. I do not have any significant drone issue. Even stock exhaust had a little drone under certain perfect conditions. The Sport is almost silent during cruise. But, under load, it is deeper and healthier. I think people are confused about the drone. I bet any louder exhaust has as much drone or more than the Eisenmann. Name one aftermarket exhaust where 100% of the people say no drone.
I can't imagine why anybody would want something louder than the Sport combined with an Xpipe and high flow cats. It sounds terrific.
