A performance slip-on muffler that provides an edge. That's how we describe our newest slip-on offering for the 2023 KTM SX-F and Husqvarna FC dirt bikes.
Our stainless/aluminum Signature Series RS-12 slip-on not only provides additional power, but it increases the torque on your SX-F or FC. We even took the extra step to include a USFS approved spark arrestor in every slip-on, giving you peace of mind when you're headed out to the wilderness. With the SA-19-K spark arrestor, your bike will be noticeably quieter, and when you're out in the deep, everyone can appreciate less dB's.
Just like all Yoshimura mufflers the RS-12 needs to be serviced from time to time so if you need to repack or rebuild it we have all the components to provide your RS-12 long life.
Weight: RS-12 stainless/aluminum muffler w/spark arrestor: 7.6 lbs. VS Stock muffler: 6.1 lbs.
SA-19-K Spark arrestor is included and installed.
Developed and tested in the heat of over 24 months of factory level racing
Aggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume that helps manage sound, add power and provide more clearance for tire and brake caliper
Improved performance gains and fit when compared to previous generation design
Just like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints. Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance
Works-look matte carbon fiber end cap with industry leading design and innovation end cap detailing as expected from Yoshimura
Carbon end cap covers inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry
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 RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
Proudly designed, developed and made in the USA!
Repack Kits, optional Inserts and Spark Arresters are available for all models
