The race bred R-11Sq from Japan is here for the current gen Suzuki GSX-R! They go together like peanut butter and jelly.

The R-11Sq is used by the Yoshimura Suzuki World Championship Endurance Team (SERT) and has been refined in the crucible of Endurance racing. This profile is iconic for Yoshimura and just bleeds cool factor.

Available in two finishes, a satin stainless steel and a beautiful blued titanium sleeve, both options incorporate the beautiful R-11Sq carbon fiber end cap.

Richard W. ★★★★★

The fit on my 2017 GSX-R1000 was absolutely perfect, no wrestling or shims needed to align the hangers. I’m still amazed how much the bike shed weight, and the stainless muffler has a clean, factory-plus look that doesn’t scream aftermarket.

Matthew I. ★★★★★

The deep, aggressive tone at 3k rpm is exactly what I wanted for my GSX-R, and the stainless muffler looks clean. It bolted on without any fuss using the stock hangers. The difference in throttle response over the heavy stock pipe is night and day.

Eli I. ★★★★★

The mid-range punch is noticeably stronger than stock, and the stainless construction looks like it will hold up to track days. Installation was straightforward with the included hardware. Really brought the bike to life.
