Yoshimura · RS-5 · Slip-On
The Yoshimura RS-5 Slip-On Exhaust / Carbon Muffler brings race-inspired styling to the Honda CBR600RR 2007–2008. Built around the RS-5’s signature trapezoid-shaped sleeve and finished with a carbon fiber end-cap, it’s designed to complement modern under-tail sportbike lines while keeping a clean, performance-minded look.
As part of Yoshimura’s Street Series Exhaust System lineup, this slip-on uses a straight baffle for ample flow and includes a removable low-volume insert. Yoshimura reports it is 2.52 lbs lighter, making it a smart upgrade for riders who want a sharper appearance and a more focused exhaust setup on their 2007–2008 CBR600RR.
Development
The RS-5’s trapezoidal sleeve shape is a signature Yoshimura look that captures the spirit of racing. Its profile is designed to visually match the race-inspired lines of under-tail muffler configurations, giving the CBR600RR a purposeful, modern silhouette without changing the slip-on simplicity.
Sound
A straight baffle design provides ample flow and supports the RS-5’s performance-focused character. The muffler also uses a large volume of packing material, and it features a removable low-volume insert, giving the system a well-considered internal layout for street use.
Materials
This configuration pairs a carbon construction with a carbon fiber end-cap and a stainless steel tail-pipe. The combination adds a premium, track-inspired finish to the rear of the bike while keeping the RS-5’s distinctive cone end-cap styling that Yoshimura is known for.
Engineering
Developed under Yoshimura’s Street Series Exhaust System banner, the RS-5 slip-on is built around the brand’s proven RS-5 layout. Key design elements include the trapezoid-shaped sleeve, a straight baffle core, and generous packing volume. This version is specified as Carbon, and it’s finished with a carbon fiber end-cap and a stainless steel tail-pipe for a clean, race-inspired presentation.
For riders who value measurable changes, Yoshimura reports a verified benefit: 2.52 lbs lighter. That reduction is tied directly to this RS-5 slip-on setup, offering a clear, manufacturer-stated advantage while maintaining the styling and construction details that have made the RS-5 one of Yoshimura’s most recognized muffler designs.
