EXHAUST SIGNATURE RS-4 FULL-SYS SS-AL-CF DUAL | 116600D320

RS12

After over three years in development and testing we are pleased to announce the RS-12 is here! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, our RS-12 has now arrived.

We 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 our new dirt bike system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system is next level.

• Aggressive, asymmetrical shaped RS-12 profile maximizes muffler volume, manages sound, adds power and provides more clearance for tire and brake caliper.
• RS-12 systems utilize precision machined joints.
• Works-look matte carbon fiber end cap with intricate details.
• New carbon fiber cap eases servicing as compared to other sandwich mounting designs most commonly found in the industry.
• New patent pending Precision Taper Fit (PTF) insert ring
• Tapered muffler body inlet design.

Building performance exhaust systems for the factory race efforts improves our research and development, which improves the overall performance of our products. Adapting technology we learn on the track to our consumer products is what makes the Yoshimura name synonymous with quality and performance. One look at our RS-9 and RS-4 exhaust systems illustrates the endless cycle of development. Working in conjunction with the factory teams has provided us with new ways to increase performance, lower sound levels and centralize mass. The end result is a product that gives you an unparalleled competitive advantage.
