Harley-Davidson and Dr.Jekill & Mr.Hyde means power, performance and design. What unites all Harley riders, regardless of age, gender or background, is that they are all freedom-loving individuals. “The Exhaust” by Dr.Jekill & Mr.Hyde is the perfect complement to take this feeling of freedom to the extreme. The Jekill and Hyde Company offers motorcyclists the ultimate riding experience with an electronically adjustable exhaust system that allows you to switch between three different performance modes on the road. A J&H system completes every Harley in terms of performance, design and sound.

We are certified Dr.Jekill & Mr.Hyde dealer and offer all J&H exhaust systems with approval. In addition, all Thunderbike Power air filters are available with combined certification and are therefore permitted with J&H exhaust systems.
