Yoshimura RS-2 Enduro Stainless Slip-On Exhaust with Aluminum Muffler | Kawasaki KLX300R 2021-2026 | USFS Arrester Installed

The Yoshimura RS-2 Enduro Stainless Slip-On Exhaust is a bolt-on muffler for the 2021-2026 Kawasaki KLX300R, built with a stainless steel mid-pipe and a pyramidal aluminum RS-2 canister, and supplied with a USFS-approved spark arrester already installed.

The pre-installed arrester is the point of the Enduro Series. A KLX300R is an off-road machine that lives on public land, where an approved spark arrester is required and checked at the gate — and most performance mufflers arrive without one, leaving the owner to buy an insert separately before the bike can legally turn a wheel. This one is compliant out of the box.

The RS-2's pyramidal canister increases internal packing volume over a round muffler of the same footprint, which is what lets it add power and improve delivery while running quieter than the pipe it replaces.

• Bolt-on slip-on muffler — retains the stock header
• Stainless steel mid-pipe with pyramidal aluminum RS-2 muffler
• USFS approved spark arrester installed from the factory
• Larger core and increased packing volume for better delivery and lower sound
• Low-volume sound insert capable for sound-restricted events
• Yoshimura part number 961-3416 (manufacturer part 243002C350)
• Made in the USA by Yoshimura R&D of America

Fits the 2021-2026 Kawasaki KLX300R as a direct bolt-on to the stock header, and is trail-ready for US Forest Service areas, BLM land and OHV parks the day it goes on. Note this is the KLX300R off-road model — the street-legal KLX300S and KLX300SM use part number 960-9517 instead.
