Yoshimura Full System Exhaust Ktm/Husqvarna SX-F/FC450 RS-12 Sign. FS/SS/SS/CF


This new system is the first Yoshimura production motocross exhaust to incorporate a resonator on the header and in the muffler. This new header resonator unlocks bottom and midrange power to not only make the new Austrian bikes more powerful, but provides more rider connectivity.
