A Yoshimura full exhaust system replaces your complete stock system from the muffler to the headers resulting in a lightweight and high performing exhaust. Be sure to update your bike's fuel map in order to take advantage of the less restrictive exhaust flow. Yoshimura's research and development experience in racing applications shine through in each of their full systems so you can bring track performance to your ride. Their high quality standards produce an attention to detail that is derived from old world craftsmanship. Each Yoshimura full exhaust system sold by RevZilla is made in the United States of America.
