Yoshimura Enduro Series Dirt Bike Exhaust

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 USFS-approved spark arrestor, forest-friendly noise levels, and are tailpipe emissions compliant.

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 your favorite enduro machine.

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 with factory level race teams
• 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
• 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 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 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
