Yoshimura · RS-3
The Yoshimura Sound Insert Kit RS-3 / TRS Mufflers, Street (TEC-SB-B) is a replacement low-volume insert kit designed for Yoshimura RS-3 and TRS street mufflers. It’s intended for riders who need a service replacement insert or want an optional insert solution when an application calls for different sound restrictions.
This kit’s decibel reduction is application-dependent. It includes a low-volume insert and a set screw, providing the core parts needed to add or replace the insert in a compatible RS-3 or TRS street muffler setup.
Built specifically as a low-volume insert kit for Yoshimura RS-3 and TRS street mufflers. It’s positioned as a replacement service part, making it a practical choice when refreshing a worn or missing insert on the muffler series it’s intended to support.
Offered as an optional kit for applications that require different sound restrictions. Because requirements can vary by setup, Yoshimura notes that decibel reduction depends on the application where the insert is installed.
Supplied as a kit with the essential components listed by Yoshimura: a low-volume insert and a set screw. This keeps the focus on straightforward replacement or addition of the insert without needing to source the primary fastener separately.
Sound
Part of Yoshimura’s Replacement Service Parts line, the TEC-SB-B Sound Insert Kit is intended to support ongoing maintenance of RS-3 series street muffler setups and related TRS street mufflers. Whether replacing an existing insert or adding one for an application that calls for a different sound restriction, this kit is centered on the specific insert components rather than a complete muffler system.
This kit is described by Yoshimura as a low-volume insert solution, but the actual decibel reduction depends on the application. Differences in muffler configuration and overall setup can influence the end result, so this insert should be selected with the understanding that sound output may vary based on where and how it’s used.
Included
Yoshimura lists the kit contents clearly: a low-volume insert and a set screw. For riders who need a replacement insert kit for their RS-3 or TRS street muffler, the included parts target the essential pieces needed to install and secure the insert.
