p>The best of both worlds. Our first foray into the concept of the hybrid MX system has been with the Honda CRF450RWE, where the durability of the stainless steel header and a light weight titanium muffler reaps rewards without sacrifice. The benefits of the hybrid system revolves around using a stainless steel header where durability is an issue, but focusing on a lighter version of the muffler where we can save big on weight. This concept finds a sweet spot at the intersection of durability. weight, and budget. Massive Power Gains Throughout the entire power spectrum our engineers outperformed the stock unit at every RPM. Even torque across the spectrum is improved. Up 9.3% hp gains at 6,200 rpm and up to 9.6% torque is achieved at 6,200 rpm. Even all the way up to the top our hybrid RS-12 system has substantial performance.

Features:

• 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
• New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arrestors
• Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
• Proudly designed, developed and made in the USA!
• 109db Capable with INS-39K insert (sold seperatly)
