Yoshimura RS-4J Race Exhaust - Honda CRF 250 L

Yoshimura is renowned for its Research and Development. But producing the finest exhaust systems in the world requires more than a big R&D department. Yoshimura is the leading manufacturer of exhaust systems because their commitment to R&D is matched by their dedication to uncompromising quality standards and their expertise in manufacturing pipes that meet those standards. From the company's beginning, they've understood that cutting-edge research and development sets Yoshimura apart from the competition. That's why they built a completely separate facility dedicated only to R&D. Creating an environment where everyone is focused on a single mission allows their talented technicians to develop improved designs while continually raising the bar on product quality. The Yoshimura motto is simple and has not changed since the company's inception: Make the best parts possible, and never compromise.
