Yoshimura RS-12 Signature Series Full Exhaust System

Yoshimura Signature Series exhaust components are the answer for riders faced with ever-tightening noise and emissions regulations at the federal level. All Signature Series components are independently tested, documented, and marked as required by state and federal regulations as CARB/EPA-compliant.

Yoshimura considered all the details when it came to the RS-12. One look and you can see it’s like nothing else on the market. As you get closer you will notice the details in every place on this dirt bike exhaust system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system is next level.

Developed and tested in the heat of over 24 months of factory level racing

Aggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume that helps manage sound, add power and provide more clearance for tire and brake caliper

Improved performance gains, weight reduction and fit when compared to previous generation design

Just like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints

Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance

Works-look matte carbon fiber end cap with industry leading design and innovation end cap detailing as expected from Yoshimura

Carbon end cap covers inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry

Patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound insert or spark arrestor

Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance

Made in the USA
