THE THREE SOUND MODES

Our exhaust systems embody three different personalities: the Dr. Jekill mode, the Dynamic mode, and the Mr. Hyde mode. With a simple press of a button, a valve inside the muffler opens or closes, giving your exhaust more power and sound. You can choose to ride in Dr. Jekill mode, Dynamic mode, or Mr. Hyde mode, depending on the situation. Whichever mode you choose, you are always 100% legal.

* Blackbox systems (motorcycles without CAN bus) have two sound modes.

STREET LEGAL, SOCIAL SOUND

Dr. Jekill & Mr. Hyde | The Exhaust is a fully legal exhaust system that complies with European laws and is ECE, EG-BE, and TÜV approved. The reason for this is that every Dr. Jekill & Mr. Hyde system includes 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 binding the system to the parameters set in EU legislation, the Smartbox intervenes smoothly and subtly when necessary. Riders do not have to worry about breaking the law in any situation. The system is always legal, no matter which sound mode is selected.

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