Description

Yoshimura has been working extensively with OE’s and factory racing teams to develop racing-oriented parts that can also benefit the weekend warrior. Because we take racing seriously, we have utilized the most technologically advanced 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 our racers, we have tuned everything from intakes to exhausts, and engines to engine management systems. Yoshimura is proud to play a role in the continuing development of UTV performance and racing.

The Yoshimura Signature RS-2 full system exhaust is engineered to enhance the performance of Yamaha YFZ450 models from 2004 through 2009. Utilizing advanced data acquisition and GPS tracking technology, similar to those used in Formula One racing, Yoshimura has developed a high-performance exhaust system that delivers increased power, improved throttle response, and a distinct racing sound. Designed with input from professional racers, this exhaust system ensures optimal tuning across various riding conditions, making it suitable for both competitive racing and recreational use.

The exhaust features a durable diamond-shape muffler that provides an aggressive aesthetic and efficient airflow management. Its maximized internal volume promotes better exhaust flow, contributing to increased horsepower and torque. The straight, single-core baffle design enhances sound quality and performance, while also making maintenance straightforward. Compatibility with spark arrestor and sound insert allows riders to comply with local noise regulations without sacrificing performance.
