YOSHIMURA R&D OF AMERICA ANNOUNCES UTV PERFORMANCE EXHAUST AND HARD PART APPLICATIONS

CHINO, CA (February 14, 2012) – Yoshimura R&D of America is proud to announce a line of performance exhausts and hard parts for the extremely popular UTV market. In recent years, UTVs and Side x Sides have emerged as one of the top off-road sports. We were excited for the opportunity to put our knowledge, skill, and craftsmanship forth and develop performance products for these machines. In order to produce the most functional and durable products available, we had to find someone who could test and abuse them on a regular basis. No one fit the bill better than William Yokley of Yokley Racing. William is no stranger to riding or the podium. He began riding as a child, racing by age 15, and has since captured several ATV and UTV Championships, including the Baja 1000.

Yoshimura has been working intently with Yokley Racing to develop parts specific to racing, while also benefiting the weekend warrior. Because we take racing very seriously, we utilized the best technological equipment available. Through the use of high-tech data acquisition and GPS tracking technology, similar to those used in Formula One racing, we’ve developed the best performing products in the industry. With additional input from Yokley and his team, we’ve tuned intakes, exhausts, engines, engine management, and fuel – everything conceivable for the best performance possible. Yoshimura is proud to play a role in the development of UTV performance and racing.

The RS-8 slip-ons are manufactured from polished 304 stainless steel and feature a deep draw polished stainless steel end cap. The muffler itself is quite innovative. It features multi-staged construction that starts with a straight baffle that initially flows into a large volume perforated baffle chamber. From there gases flow into a floating baffle that is integrated into the end cap. In side the floating baffle is a USFS approved spark arrestor. Low 96dB sound levels keep the RS-8 friendly on the trails. The overall design produces big increases in power and torque.

The RS-4 is a technological marvel and packed with features, like a Carbon Fiber end cap a first in the UTV market, a USFS approved spark arrestor, Yoshimura’s exclusive resonance chamber and 2-stage stepped internal baffle, this effectively acts as a mechanical system and in turn improves power while lowering dbs.

The RS-2D (Dual Muffler) is a really versatile and very potent pipe. It is basically an evolution of our original TRC design but with a slightly different (pyramidal) shape that features increased volume. The volume enables a quieter system and larger cores; this in turn increases power and power delivery. Comes with a USFS approved spark arrestor.

Yoshimura will have a host of slip-on, full systems and hard parts available soon for the most popular makes, models and applications.


UTV Full Systems

These Full Systems pull out all the stops. Each is CNC mandrel bent using 304 Stainless Steel tubing for a long lasting, durable and rust-resistant life. Headers feature an over-sized step tube design for maximum power through out the entire RPM range. Our systems not only out perform stock exhaust systems, they weight less too.

Yoshimura Slip-On

RZR XP 900: Carbon Fiber Intake Scoops

The stock RZR XP 900 intake panels are adequate, but we needed something better. We designed these Air Scoops to fit over the stock intake ports, providing maximum air-flow to the engine. They are not only extremely functional, but lightweight and styled to compliment the RZR’s sharp lines.

Yoshimura RZR XP Air Scoops

RZR XP 900: Carbon Fiber Mirror Kit

While most of our R&D focuses on maximizing performance, we’re also concerned about safety. The more we ran our XP at the track and off-road, the more we desired mirrors. This kit is simple to install and the convex mirror provides much needed vision behind you. Similar to our air scoops, they feature lightweight carbon/aluminum construction and styled for the XP.

Coming Soon…


RZR XP 900: Aluminum Racing Roof

Spending all day in your XP is a blast! But the sun and environment can eventually take their toll on the best of drivers. We designed our Aluminum Racing Roof to be provide maximum protection from the sun, keeping in-car temperatures more pleasant for driver and passenger. Aluminum keeps the weight down, but sturdy enough for the harshest of conditions.

Coming Soon…


RZR XP 900: Aluminum Wind Deflector

The Aluminum Wind Deflector provides even more comfort for all day excursions. By deflecting air upward from the front of the car, it reduces turbulence and helmet buffeting, allowing the driver to remain focus and less fatigued. The deflector also limits the amount of dirt, mud, and debris hitting the occupants while racing or trailing others off-road.

Coming Soon…


RZR XP 900: Radiator Roost Guard

The Radiator Roost Guard was one of the first products we developed for the RZR XP. Protecting your radiator and maintaining coolant temperatures is important in all aspects of driving. While racing, we found a lot of mud and debris accumulated on the radiator causing undesirable temperatures. The Radiator Roost Guard deflect debris off to the side allowing your radiator to remain clear and do it’s job. This is a great alternative to spending hundreds more on radiator relocation kit.

Coming Soon…
