Yoshimura · R-77
The Yoshimura R-77 Replacement End Cap Kit Slash-Cut Right Side is a service-parts solution for right-side R-77 mufflers that use a round, slash-cut outlet. Built for an end cap swap, this kit is designed to replace the end cap while keeping the look and function consistent with the R-77 series.
Manufactured by Yoshimura R&D of America, Inc., this high-gloss carbon fiber end cap is made in the composites shop in Chino, California using heat resistant impregnated, lightweight carbon fiber. It also includes the associated hardware needed for installation, helping streamline the replacement process.
This replacement end cap kit is intended for right-side R-77 mufflers that feature a round, slash-cut outlet. It matches the outlet style specified for those mufflers, making it a focused service-parts option when an end cap needs to be swapped rather than replacing the entire muffler.
Yoshimura produces the end cap in its composites shop in Chino, California. The end cap is described as heat resistant impregnated, high gloss, lightweight carbon fiber, delivering the premium carbon look associated with Yoshimura components while serving as a direct replacement part.
Beyond the end cap itself, the kit includes supporting pieces used during an end cap swap: rivets, a rivet band, and an insert hole grommet. Having these items together helps ensure the needed installation components are on hand when servicing an R-77 muffler end cap.
Fitment
As part of Yoshimura’s Replacement Service Parts line, this R-77 end cap kit is intended to support maintenance and repair on an existing exhaust. The kit’s focus is straightforward: provide the end cap and the related small parts needed to complete an end cap swap on compatible right-side R-77 mufflers with a round, slash-cut outlet.
Materials
Yoshimura notes that this end cap is made in its composites shop in Chino, California. The carbon fiber is described as heat resistant impregnated, high gloss, and lightweight, aligning the replacement component with the appearance and purpose expected from an R-77 series carbon fiber end cap.
