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.

Want to remove the sparky and head to an MX track? No problem! Pull out the PTF insert system that makes it a breeze to install and remove spark arrestor or low volume insert.

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.

RS-12 is proudly designed, developed and made in the USA.
