The RS-4 Race Series slip-on gives the CRF250L more power and torque, the RS-4 provides more punch at bottom end without sacrificing the mid and top power. The slip-on also removes a good amount of weight from the stock unit. Those that love the Yoshimura RS-4 sound will love the way it makes the CRF250L Rally sing!
