The new Suzuki 800 twin platform packs quite a punch for a parallel twin! Yoshimura brings you the uncompromising power of our Speed Series 49 state friendly system for the new GSX-8R/S.

Our engineers knocked it out of the park on this one! The product of months or development, an AT2 Speed Series Works Finish full system with a carbon fiber heel guard and packed with some impressive new power for the new 776cc, 270-degree engine… the results are astounding! The new Suzuki system comes to life on the dyno adding a Max HP of 5.7% paired with a torque gain of 6.1 percent. As if all the new power wasn’t enough, the new Speed Series system even manages to trim a whopping 6.5lbs of weight over the stock unit. There's no mistaking the signature Yoshimura sound and a GSX-8S/R equipped with this new 49-state friendly system delivers a sonic tone that does not disappoint!

Also available as an option for this full system is our Low Volume Insert INS-20-K and our Aluminum Muffler bracket kit 200BG117200*.

*Muffler bracket kit not compatible with GSX8T/TT

Yoshimura's AT2 is proudly designed, developed and manufactured in Chino, California.

David X. ★★★★★

The welds and brushed stainless finish look even better in person than in the photos, and the tone is deep without being obnoxious on the highway. Install was straightforward, and I can feel the midrange pull right away.

Emily ★★★★★

Took about 45 minutes to swap out the stock system on my 2025 GSX-8T, and the stainless muffler's finish is flawless. The bike sounds deeper and feels noticeably punchier at mid-range throttle openings. Couldn't be happier with how it transformed the riding experience.

Nicholas ★★★★★

Mounted it on my 2024 GSX-8R this weekend and the stainless construction feels rock solid, plus that deep bark at 4k rpm is exactly what this twin needed. Took about three hours with the included hardware, and the weight savings over the stock can are noticeable when you flick it through corners.
