Yoshimura RS-9 Full Exhaust fits 2017-20 CRF450r and 250r. Off 18’ CRF 450r. It may also fit the 250r as well. Overall shape is good, a couple small rock dings in header, cosmetic damage to right side carbon tip as seen in pic. New one can be put on but really doesn’t need it. This exhaust will bring your bike to life, best bang for the buck power added on. If you have any questions let me know.
