Whether you are a casual play rider or a hard-core racer, Bill's Pipes can bring your bike to life. Made of 304 stainless steel with lightweight 6063 aluminium mufflers, our line of Thunder Series exhaust systems are designed to maximise the true performance that lurks within your ride. Our pipes weigh in at less than your original cumbersome steel exhaust system. Unique to the Bill's Pipes Thunder Series exhaust system is our trademark billet aluminium end-cap that is not only stronger and more durable than those found on other systems, but better looking as well.
All Thunder Series exhaust systems are developed with more real, usable power in mind. Better throttle response, stronger mid-range and more top-end pull can be gained, simply by installing one of our systems on your bike. Hand-made in the USA, each pipe is manufactured to strict quality control guidelines, and all are guaranteed to fit perfectly and hold up to the rigorous abuse of hard riding on the track or trails.
