Yoshimura Signature Series Dirt Bike Exhaust

Introducing Signature Series by Yoshimura - an offering of exhaust systems that a dealer can install with confidence. Our 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 of our off-road applications. Everyone of our Championship Winning Motocross exhaust systems and nearly all of out 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.

After three years of development and testing Yoshimura is pleased to announce the RS-12 full system exhaust! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, the RS-12 has now arrived for the Honda CRF.

One look and you can see the RS-12 is like nothing else on the market. As you get closer you will notice many performance details placed throughout the system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system takes it to the next level.

Features:

• Developed and tested over 24 months of factory level racing
• Aggressive, intelligently designed, asymmetrical shape of the RS-12 allows for maximum muffler volume which helps manage sound, add power and provide more clearance for the rear tire and brake caliper
• Improved performance gains and weight reduction
• Just like the works systems Factory Racers use, RS-12 systems utilize precision machined joints which provide a superior fit and improve system life and performance
• Works-look matte carbon fiber end cap with industry leading design
• Carbon end cap covers inner cap mounted design which improves durability and eases servicing as compared to other sandwich mounting designs
• 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 the 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

The work that went into developing the RS-4 muffler design paid big dividends in 2010 with Ryan Dungey winning the AMA 450 Supercross and Motocross Championship series as a rookie in the same year, and again in 2012 with the Yoshimura-backed GEICO Honda team 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 features a Polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.

Features:

• Pentagonal-shaped sleeve
• Front muffler cap functions as a polyresonant chamber which helps reduce noise
• Two-stage stepped baffle

Introducing the all-new RS-9 Dual. The CRF’s new dual-muffler configuration gave us the opportunity to create an entirely new muffler built specifically for the dual-muffler CRFs. We worked with Top AMA Pro Riders to achieve maximum performance and mass centralization, and to optimize rider usability. We achieved all this while maintaining AMA Regulation sound levels. The RS-9’s uniquely sculpted Carbon Fiber end-caps feature a Tunable Insert System, so you can fine-tune power delivery and decibel levels to your specifications.

Features:

• Parallelogram-shaped muffler
• Increased muffler volume over stock system, resulting in better throttle response and improved noise cancellation
• Light-weight muffler construction with carbon fiber end-cap
• CNC machined muffler bracket
• Reduced weight over OEM system
• Vertical tail-pipe divider splits the exhaust gases more evenly, for smoother flow, which improves mid-top power and throttle response

• All applications are marked with appropriate EPA noise emissions labels
• Certified by an independent laboratory for EPA noise compliance
• Yoshimura has been working tirelessly on development with American Honda HRCs engineers to achieve maximum performance and mass centralization, to optimize rider usability. Yoshimura achieved all this by moving the RS-9T mufflers forward in order to tuck in under the side number plates. Working with HRC race engineers and the 449cc Unicam engine and its unique downdraft fuel injection system, Yoshimura was able to deliver an exhaust that provides more tractable power and improved torque.
• Dyno and track tested by Honda R&D; in Japan, American Honda MX Team, and HRC All Japan MX Racing Team
• 3-stage header provides broader overall range of power and throttle response
• Tail pipe divider creates smoother exhaust flow and better velocity to the right and left tail pipe
• Compact forward positioned RS-9T dual muffler design provides lower center of gravity for better mass centralization
• Larger RS-9T core creates improved throttle response, and power in mid and top end
• RS-9T mufflers have more volume than stock to provide a decrease in overall dB noise level
• Works with or without Hondas new optional electric start system

The RS-2 is a potent and versatile design that evolved from our original TRC, engineered to provide increased power and power delivery. With a different pyramidal shape that features increased volume, the RS-2 is a quieter system with a larger core — and it offers the added bonus of outstanding performance in a value-priced package.

Features:

• Diamond-shaped sleeve
• Large core and increased muffler packing volume means quieter operation
• USFS Approved spark arrester included

The RS-4 Twin Pipe kit was previously only available as a custom system for Kevin Schwantz who was passionate about these pipes on his Super Motard. He wanted his motorcycle to look like a "Hot Rod" and have a "cool" factor. We obliged and one of our most sought-after-yet-unobtainable pipes was created, which was not available to the general public, until now.

Yoshimura is offering these incredible “Twice Pipes” which are completely fabricated by hand and TIG welded to perfection. They certainly sit at the high end of what is available for the mighty SM... but that's what Kevin wanted! The pipes have a stainless steel header and "Y" pipe mated to twin carbon fiber RS-4 mufflers for incredible looks and performance. The kit also comes with a custom Yoshimura kick-stand.

Features:

• RS-4 "Twin Pipe" Exhaust
• Kevin Schwantz Supermotard Design
• Pentagonal-shaped sleeve
• Front muffler cap functions as a polyresonant chamber which helps reduce noise
• Two-stage stepped baffle
• Includes new custom kickstand

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 takes it to the next level.

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