Designed as a replacement low-volume insert kit for TRS mufflers, this Yoshimura kit provides the components needed to restore or change the insert setup on compatible TRS 4.5" muffler applications.
Yoshimura lists this kit as an optional solution for applications requiring different sound restrictions. Because decibel reduction depends on application, it offers a practical way to tailor sound output based on the specific bike and configuration.
The kit includes a low-volume insert tube, an end-cap collar, and a set screw. These components are intended to work together as a matched insert assembly for TRS muffler use on the listed fitments.
Sound
This Yoshimura sound insert kit is built around a low-volume insert tube and supporting hardware intended for TRS mufflers. It can serve as a replacement service part for a worn or missing insert, or as an optional insert choice where different sound restrictions are required for a specific application. Because sound change varies by setup, the exact decibel reduction depends on application.
