Yoshimura · RS-2
The Yoshimura RS-2 Premium Muffler Repack Kit is a replacement service parts kit designed to refresh RS-2 off-road mufflers at the intervals Yoshimura recommends. Yoshimura notes that off-road systems should be repacked after 6-8 hours of use, or after each Race, to help the exhaust perform as intended.
Dirty packing can restrict airflow from the motor, leading to a loss of power and degraded sound. By renewing the packing, this kit helps restore freer airflow, bringing back lost power and improving exhaust sound. See the fitment table below for the supported Honda, Kawasaki, Suzuki, and Yamaha applications and model years.
Performance
This kit includes Premium Fiber Packing Material intended to replace worn or dirty muffler packing. Yoshimura explains that fresh packing supports freer airflow from the motor, which can restore lost power and improve the exhaust sound when repacked at the suggested service intervals.
Included
Sixteen Stainless Rivet pieces (C3-RIVET x 16 QTY) are included to support proper reassembly after servicing. Having the specified rivets on hand helps keep the repack process straightforward and aligned with the parts called out for this RS-2 kit.
Installation
Four Rivet Bands (LC4.5T x 4 QTY) are provided along with a Muffler Decal, Wrap-Around. These components help complete the service job with the hardware and identification elements listed for the RS-2 Premium Muffler Repack Kit.
Performance
Yoshimura states that off-road systems need to be repacked after 6-8 hours of use, or after each Race. Following that schedule is described as essential for the exhaust to perform the way it was designed. As packing becomes dirty, Yoshimura notes it can restrict airflow from the motor, which results in a loss of power and a degradation of sound.
Sound
According to Yoshimura, repacking the muffler allows for freer airflow from the motor. That restored flow is described as helping to bring back lost power and improve exhaust sound. This kit is built around that service goal, providing the packing material and associated parts listed for the RS-2 repack procedure.
