The work that went into developing the RS-4 muffler design paid big dividends in 2010 with winning the AMA 450 Supercross and Motocross Championship series, and again in 2012 winning both 250 Supercross Lites titles. That same R&D has been directed to developing the current generation RS-4 - a unique design that provides an unrivaled combination of power and a quiet exhaust note.
The RS-4 Slip-On uses the same technology that goes into the full systems, but features an easier-to-install application. The RS-4's premium muffler packing helps meet the U.S.F.S. noise specifications while maintaining performance. The RS-4 features a polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.
Front muffler cap functions as a polyresonant chamber which helps reduce noise.
Two-stage stepped baffle.
Carbon fiber end-cap (most models).
Stainless steel tail-pipe.
Yoshimura Exhaust Series Descriptions:
Enduro Series: In the mid 90's Yoshimura didn't go to the dirt; the dirt came to Yoshimura. Enduro Series systems are an evolution of Yoshimura's early off road efforts crafting off-road exhaust systems. The Enduro Series are all equipped with U.S.F.S.-approved spark arrestor, forest-friendly noise levels, and are tailpipe emissions compliant. (CARB/EPA tail-pipe emissions compliant; all applications are marked with appropriate EPA noise emissions labels.)
Race Series: If you're looking for that competitive edge, look no further than Yoshimura's Race Series. These exhaust systems are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. FOR CLOSED COURSE COMPETITION ONLY; NOT INTENDED FOR STREET USE.
Signature Series: Introducing Signature Series by Yoshimura - an offering of exhaust systems that a dealer can install with confidence. The Signature Series lineup is the answer for today's dealer who is faced with a challenging marketplace. The applications for the Signature Series line cover the entire powersports spectrum, including many off-road applications. Everyone of Yoshimura's Championship Winning Motocross exhaust systems and nearly all of the ATV / Side-by-Side applications are all members of the Signature Series Family. All Signature Series components are tested, documented, and marked as required by federal and state regulations. (CARB/EPA tail-pipe emissions compliant; all applications are marked with appropriate EPA noise emissions labels and certified by an independent laboratory for EPA noise compliance.)
Street Series: All Street Series systems are slip-on / bolt-on applications that do not require tampering with the vehicle's emissions control system, yet still deliver that special spirit the world has come to expect from the legendary company known as Yoshimura. Street Series applications cover all of the iconic profiles that Yoshimura has become famous for. From the legendary tri-oval profiles to the refined carbon fiber R-77 mufflers, and even the R-55 angular masterpieces. Yoshimura's Street Series exhaust offer street-legal options for almost everything on two wheels. (CARB/EPA tail-pipe emissions compliant; all applications are marked with appropriate EPA noise emissions labels.)
