Yoshimura RS-12 Slip-On Exhaust Honda CRF300L / Rally

Yoshimura's long standing relationship with Team Honda HRC facilitated the research and development of the optimal slip-on muffler for the 6th generation CRF250R platform well ahead of the competition. Not ready for a full swap? The RS-12 slip-on with spark arrestor still crushes it with up to 7.0% HP gains at 5,000 RPM and 7.5% torque boost at the same peak – perfect for quick installs and immediate gratification.

One look and you can see the RS-12 is like nothing else on the market. As you get closer you will notice many performance details placed throughout the slip-on, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this muffler takes it to the next level.

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

Weight:

• Stock muffler: 10.0 lbs.
