The internal combustion engine is really quite simple when you break it all down. It is basically just a mixture of fuel, compression, spark and air forced in one way and out the other. Getting more horsepower out of it is a matter of increasing things from one direction to the other and there are many ways to do so. One of those ways, and a popular one for the Polaris RZR at that, is by bolting on a different RZR exhaust system.
Yoshimura R&D of America has introduced a line of performance exhausts and hard parts for the UTV market.
“In recent years, UTVs and Side x Sides have emerged as one of the top off-road sports,” Yoshimura says in a release. “We were excited for the opportunity to put our knowledge, skill, and craftsmanship forth and develop performance products for these machines.”
To thoroughly test out the new lineup, Yoshimura teamed up with William Yokley of Yokley Racing, winner of countless ATV and UTV race, including the Baja 1000
“Yoshimura has been working intently with Yokley Racing to develop parts specific to racing, while also benefiting the weekend warrior,” Yoshimura says in the release. “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.”
