Yoshimura - RS-4 Signature Series Slip-On (KTM)
Development takes time and the Yoshimura's KTM 450SX-F application now has the answer for real power when it comes to exhaust. These kind of gains in power and torque don't come overnight, but are developed in testing, in the dyno room and on the race track. Available as an aluminum.carbon fiber slip-on, the Yoshimura RS-4 Signature Series Slip-On will not dissapoint.
