RS-12 Stainless Full Exhaust, w/ Aluminum Muffler
 
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
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, innovation and detailing as expected from Yoshimura.
Carbon end cap covers an inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry.
New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.
Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
Repack Kits, optional Inserts and Spark Arresters are available for all models
