I've wanted to switch to eisenmann but have a heard that the race version, whereas it sounds great when your mashing the throttle, has a lot of drone under normal street driving, and that would bother me. I've always wondered how different the sport version sounds from stock, but no one has ever posted a comparo video. Does anyone have personal experience with that?
