Yoshimura's performance exhausts and hard parts are now available for the ATV's and UTV's and are made to be durable and functional.
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 arrester. 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 Duplex 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.
