Electronically adjustable exhaust systems

Let's start with the most important one: Dr. Jekill _ Mr. Hyde offers a fantastic, unique sound. It's as simple as that. For many motorcyclists, sound is an essential and indispensable part of their hobby and passion. The ultimate way to celebrate their freedom. Dr. Jekill & Mr. Hyde's specialized engineers have developed a tailor-made sound for every bike that offers the rider the ultimate riding experience and can be adapted to any situation. The riders' experiences are the proof!

A Dr. Jekill & Mr. Hyde exhaust allows the driver to choose between 3 different sound modes. This means that the driver can enjoy the ride with their favorite exhaust soundtrack, but can also be quiet and calm when appropriate. You can choose between a quiet, soft tone, a dynamic midrange, or a deep bass with no treble or midrange tones. With a simple push of a button, the valve in the muffler opens or closes, allowing the sound level and character to be adjusted to suit the moment while riding. This valve is located in the center of the exhaust; the optimal position for sound, performance and emissions, and is not visible from the outside, making it a perfect match for the design. (Please note: Blackbox systems (motorcycles without CAN bus) have two sound modes.)

Dr. Jekill & Mr. Hyde | The Exhaust is a completely legal exhaust system that complies with European law and is ECE, EC-BE and TÜV approved. The reason for this is that every Dr. Jekill & Mr. Hyde system contains a Smartbox: this electronic control unit is the brain of the product and contains software that reads CANBUS signals coming from the motorcycle's ECU.
By tying the system to the parameters set by EU legislation, the smartbox intervenes smoothly and subtly when needed. Riders never have to worry about breaking the law in any situation, the system is always legal no matter which sound mode is selected.

Apart from that, we also have to understand that we live in a crowded society where we have to accept that we also have to be considerate of the people around us who may not like the sound of a Harley at all. That is why we at The Jekill and Hyde Company offer the option to customize your sound to the moment. This way you can continue your favorite hobby without disturbing others.
