Yoshimura RS-9T Stainless Dual Slip-On Exhaust | Honda CRF250R / CRF250RX 2018-2019

The Yoshimura RS-9T Dual Slip-On Exhaust is a pair of bolt-on mufflers for the 2018-2019 Honda CRF250R and CRF250RX, built on Yoshimura's stainless RS-9T architecture and mounting directly to the stock headers.

This generation of CRF250R runs a twin-muffler layout, so the kit supplies both canisters. That makes it the most effective single weight change available to the bike — two stock mufflers carry a lot of mass high and to the rear, and replacing both at once removes considerably more than a single-canister swap.

The RS-9T was Yoshimura's motocross canister before the RS-12 took over, and it is the correct fitment for this chassis. Both canisters accept Yoshimura's low-volume sound inserts and spark arresters, so the same bike can run legal at a sound-tested race and on public land.
