Yoshimura · RS-3
The Yoshimura Spark Arrester Kit for RS-3 Monkey mufflers is a replacement service part designed specifically for the Honda Monkey 2019–2026. Built to work with Yoshimura’s RS-3 Monkey mufflers, this insert adds spark arresting capability while also helping reduce overall exhaust sound output on the bike.
Yoshimura states this spark arrester decreases dB level by 4 decibels on a Honda Monkey equipped with their full system, while enabling off-road travel by arresting sparks. It’s a straightforward way to refresh or update an existing RS-3 setup while keeping the exhaust configuration aligned with the intended RS-3 muffler design.
This kit is listed as a replacement USFS Approved spark arrester for RS-3 Monkey mufflers. It’s intended for riders running the Yoshimura RS-3 setup on the Honda Monkey and who need the correct replacement insert designed for that application.
Yoshimura notes that this updated spark arrester can decrease the dB level of a Honda Monkey with their full system by 4 decibels. That makes it a practical option for riders looking to take a bit of edge off sound output while keeping the RS-3 muffler configuration.
The kit includes a spark arrester insert, making it a focused service solution for RS-3 Monkey mufflers. It’s a direct replacement-style component intended to restore spark arresting function without replacing the full muffler assembly.
Sound
As part of Yoshimura’s Replacement Service Parts product line, this Spark Arrester Kit is aimed at maintaining RS-3 Monkey mufflers with the correct components for the application. Rather than changing an entire exhaust, the kit focuses on the spark arrester insert used in the RS-3 series muffler setup for the Monkey, helping keep the system configured as intended.
Yoshimura positions this insert as more than a simple replacement: it both arrests sparks and can reduce exhaust sound. According to Yoshimura, it decreases the dB level of a Honda Monkey equipped with their full system by 4 decibels, while also enabling off-road travel by arresting sparks—useful for riders who want the RS-3 sound character with a quieter output and spark control.
