The Yoshimura RS-9T Slip-On Exhaust is a bolt-on muffler for the 2020-2021 Honda CRF250R and CRF250RX, built on Yoshimura's stainless RS-9T architecture and mounting directly to the stock header.
The RS-9T was Yoshimura's motocross canister before the RS-12 took over, and it remains the correct fitment for this generation of CRF250. On a 250 four-stroke motocrosser the exhaust does a disproportionate amount of the tuning work, and a slip-on is the accessible way into that gain without replacing the header.
The canister accepts Yoshimura's low-volume sound inserts and spark arresters, so the same muffler covers sound-restricted race days and public-land riding where an approved arrester is required at the gate.
Fits the 2020-2021 Honda CRF250R and CRF250RX as a direct bolt-on to the stock header. Fit an approved spark arrester insert before riding on US Forest Service or BLM land. Contact us to confirm the exact muffler sleeve material for this part number before ordering if that matters to your build.
