Yoshimura · R-11 · Slip-On
The Yoshimura R-11 Slip-On Exhaust with Titanium Blue muffler is a Street Series Exhaust System built for the GSX-S750 model years 17-23. Developed from Yoshimura’s R-11 platform, this slip-on is aimed at riders looking to sharpen the bike’s character with a lighter setup and a more aggressive Yoshimura exhaust note.
Yoshimura reports measurable performance gains, including up to 3.8% more HP @10,000 rpm and up to 5.4% torque @7,500 rpm. With a titanium construction and a weight listing of 5.1 lbs. for the blued titanium R-11 configuration, it’s designed to reduce mass compared to the stock system while delivering the signature sound riders associate with Yoshimura Suzuki applications.
Built as an R-11 Street Series slip-on, this exhaust uses titanium for the muffler construction. The Titanium Blue finish distinguishes the canister visually while keeping the system aligned with the R-11’s street-focused design intent for the GSX-S750 17-23.
Performance claims are supported by the included dyno chart on the page. Yoshimura reports up to 3.8% more HP @10,000 rpm and up to 5.4% torque @7,500 rpm, targeting stronger pull at key points in the rev range.
The data lists the stock system at 9.9 lbs. and the Yoshimura R-11 blued titanium at 5.1 lbs., reflecting a substantial reduction in exhaust mass for the GSX-S750 17-23.
Performance
This exhaust belongs to Yoshimura’s Street Series Exhaust System lineup and uses an R-11 slip-on configuration. The R-11 is positioned as an upgrade intended to improve multiple aspects of the GSX-S experience, pairing a lightweight titanium muffler with a more assertive tone and manufacturer-verified performance claims shown with the dyno chart on the page.
Sound
For riders who care about sound character as much as performance, the manufacturer provides sound levels measured using J2825 standards. The listing includes readings at 2000 rpm and 5000 rpm for both the stock system and the R-11, giving a clear, apples-to-apples reference for how the exhaust note changes with the R-11 slip-on installed.
Development
Yoshimura states the R-11 is designed, developed and manufactured in Japan. That background matches the R-11’s reputation for being purpose-built rather than generic, with the product page also including a video and an installation PDF for additional context on the system and setup.
