Hideo "Pops" Yoshimura started the company back in 1954. Yoshimura had a humble beginning. From the original shop in Japan, however, a seed was planted and it started to grow.

The reputation of Yoshimura grew quickly. The motorcycle and racecar engines Pops built were very quick. Soon he had a following of diehard racers. In the seventies, Pops came to America and started up the American division of his company.

Yoshimura became the leading manufacturer of sportbike exhaust system by hard work, not by accident. In the old days, Pop's pipes were in such high demand that he was forced to start mass producing them. As time went by, the demand increased exponentially. Today, Yoshimura R&D ships up to 6,000 pipes per month! The reason the demand was, and is, so high is quality and performance. These two elements came about as a direct result of R&D. Yoshimura has always had an exhaustive research and development program. After all, it's our middle name. Typically the lights are on way after 5:00 each night. Our R&D group and race group integrate and interact in order to bring "cutting edge" track technology to the masses. The real difference between us and our competitors however is expertise. There is a big difference between working hard and working smart. We have been racing at the top level for so long we know what works and what does not. Our testing and R&D procedures are efficient and focused. The result is plain to see in our products...the finest in the world.
