* With the success of Yoshimura’s RS-9 dual muffler exhaust system and the 2013 CRF450R used by the Muscle Milk Honda factory team, it’s only natural that we carry over the same technology for the all new 2014 CRF250R that will set the standard again for others to follow. * The Honda CRF250R’s new dual-muffler configuration allowed Yoshimura to take advantage of the mass centralization and maximum performance while keeping the RS-9 system well within AMA regulated sound levels. The RS-9’s uniquely sculpted carbon fiber end-caps feature a Tunable Insert System that allows you to fine-tune power delivery and decibel levels to your wants and needs. And the RS-9 Dual is AMA Amateur sound legal – right out of the box. * The RS-9’s parallelogram-shaped muffler body increases muffler volume over the stock system, which results in better throttle response and improved sound quality. The dual setup also allowed Yoshimura to position the mufflers closer to the bike’s center of gravity, which results in better handling. * Slip-On includes Dual RS-9 mufflers, stainless steel tail-pipe, installation hardware and detailed instructions.
