These expertly designed and crafted exhausts have been specifically made for competitive racing. They feature stainless steel construction and have been dyno tested. The BWR Systems have been personally designed and tested by legendary flat track tuner Bill Werner!

Werner-Designed Racing Exhausts are available in a High Pipe that mounts like the stock system for ’05 – ’08 Honda CRF 450 or a Low Pipe System for C&J and J&M framerace bikes. Both systems provide substantial power increases across the entire range. Each features a complete Stainless Steel multi-stepped head pipe that runs into a 2.5” core and utilize SuperTrapp’s patenteed Tunable Disc Technology.

The Werner-Designed 2:2 Megaphone Race System and 2:2 Stepped head pipe are available for the XR750.

Select systems are also available for ’08 Kawasaki KX450F, ’05 – ’07 Suzuki RM-Z450, ’06 – ’08 Yamaha YZ450F.

These systems have their particular strengths for certain tracks and riding conditions. Most riders will find that the Megaphone System is ideal for one-mile tracks and the Stepped Head Pipe System is best suited for half-mile tracks. Both systems give racers more options for optimizing their bike’s performance on different tracks and in different riding conditions.

Our pipes are on most flat-track bikes because they take flat-track racing to a whole new level. In Werner’s words, “I’ve been using SuperTrapp products for years – since the late ‘70s – and have always been impressed with the quality and performance gains,” Werner said. “The SuperTrapp system is unique with a disc system that has instant tunability. It takes only minutes to make some adjustments that result in a significant power characteristic change in your motorcycle.”
