Yoshimura RS-12 Slip-On Exhaust Honda CRF450R

Yoshimura has leveraged its close partnership with Team Honda HRC to design the supremely engineered RS-12 slip-on muffler, ahead of its rivals for the 6th generation CRF250R. Ideal for those not ready for a comprehensive exhaust overhaul, the RS-12 comes equipped with a spark arrestor and impressively boosts performance—delivering gains of up to 7.0% in horsepower at 5,000 RPM and a 7.5% increase in torque at the same threshold. This makes for easy installation and on-the-spot performance enhancement. On first glance, the distinctive design of the RS-12 stands out from the competition. Upon closer inspection, the careful attention to performance details becomes apparent, from the matte carbon fiber end cap adorned with decal inlays to the meticulously machined connections, ensuring that the RS-12 elevates the standard for slip-on mufflers.

Features:

• Aggressive, intelligently designed, asymmetrical shape of the RS-12 allows for maximum muffler volume which helps manage sound, add power and provide more clearance for the rear tire and brake caliper
• Improved performance gains and weight reduction
• Just like the works mufflers Factory Racers use, RS-12 systems utilize precision machined joints which provide a superior fit and improve system life and performance
• Works-look matte carbon fiber end cap with industry leading design
• Carbon end cap covers inner cap mounted design which improves durability and eases servicing as compared to other sandwich mounting designs
• New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arrestors
• Tapered muffler body inlet design of the RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
• For use with OEM header
• Proudly designed, developed and made in the USA
