This kit includes one replacement USFS approved spark arrester intended for Yoshimura RS-9 off-road mufflers. It is suited for servicing an existing setup or adding an optional spark arrester on applications that did not originally come equipped with one.
Along with the spark arrester insert, the kit includes an end-cap collar and a set screw. These components are provided as a matched set to support a straightforward replacement on compatible RS-9 applications.
Yoshimura specifies that dual muffler systems require two Spark Arrester Kits. This makes it easy to order the correct quantity when servicing or converting a dual-exit RS-9 off-road muffler configuration.
