CRF250L\'17-20 - Yoshimura RS-4 SS Full Exhaust System
*** Available for back order - Do not order if you can not wait for restock to arrive ***
 
The RS-4 is a unique design with predicated power and a quiet earthy exhaust note that speaks volumes for performance. This RS-4 features all the benefits of our original RS-4 muffler, but with a unique turned-out end-cap, designed to direct exhaust heat and gases away from the bike's components. To top-it-off, we embossed our Yoshimura's "347" logo in the carbon for a clean look. An optional heat-shield can be added to the poly-resonant chamber to keep rider and passenger legs from exhaust heat. With all its benefits in mind, the RS-4 was an obvious choice for the CRF250L.
 
Full System includes an RS-4 muffler with turn-out end-cap, stainless steel header and tail-pipe, low-volume insert, all installation hardware, and step-by-step instructions.
 
FOR CLOSED COURSE COMPETITION ONLY; NOT INTENDED FOR STREET USE.
