With over 30 years of testing, engineering, and development, Bill's Pipes® is the go-to brand of champions and riders all over the world for quality-built, performance tested and race proven exhausts and accessories for 2-stroke and 4-stroke engines. To those of you with decades of motorcycle experience, Bill Cervera, the owner and namesake of Bill’s Pipes, is no stranger. You have seen his products on everything from the dirt track monsters of the 80s to the factory Hondas, Suzukis, and Yamahas of the 90s, and maybe even had a product bearing his name bolted onto your bike. Deeply interested in dirt track racing, Bill started building exhaust systems for his friend in his own garage, further growing experience together with his employees and race mates by doing dirt track stuff for American Honda and building pipes for its motocross bikes, 4-strokes and 2-strokes for Harley, making pipes for Pro Circuit and working together with many other big guys.
