Yoshimura · RS-3
The Yoshimura Sound Insert Kit RS-3 4.5" Muffler, Street is a replacement low-volume insert kit designed for RS-3 mufflers. It’s built for riders who want to service or refresh their existing RS-3 setup with the correct replacement components.
This kit is listed for applications including BMW R-NINE-T 2014–2016, Suzuki Hayabusa 1999–2019, and multiple Suzuki and Yamaha sportbike models shown in the fitment table below. With core pieces needed to reinstall a low-volume insert arrangement, it helps return the muffler to the intended street insert configuration after maintenance or replacement.
Sound
At the center of the kit is a Low-Volume Insert Tube intended for RS-3 mufflers. As a replacement service part, it’s a straightforward way to restore the low-volume insert component on an existing RS-3 4.5" muffler street setup without changing to a different muffler system.
Included
This kit includes an end-cap collar, supporting proper placement and retention of the insert components at the muffler outlet. It’s supplied as part of the replacement package to match the RS-3 series insert arrangement and help keep the parts located correctly during use.
Development
A set screw is included to secure the insert assembly. This small but important piece is part of the factory-style replacement contents, helping keep the insert in place as intended when installed on the applicable RS-3 muffler configuration.
Sound
