ELECTRONICALLY ADJUSTABLE EXHAUST SYSTEMS
Dr. Jekill & Mr. Hyde offers an electronically adjustable exhaust system for motorcycles, allowing you to adapt your sound to the moment and choose the perfect mode for every situation — all at the touch of a button. Be polite and quiet when you want to, or make yourself heard when the moment calls for it.
STREET LEGAL, SOCIAL SOUND
Dr. Jekill & Mr. Hyde | The Exhaust is a completely 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 contains a smartbox: this electronic control unit is the brain of the product and contains software that reads CAN bus signals coming from the motorcycle’s ECU.
By committing the system to the parameters set by EU legislation, the Smartbox will seamlessly and subtly intervene if necessary. Riders don’t have to worry about breaking the law in any situation; the system is always legal no matter what sound mode is selected.
That being said, we must also understand that we live in a crowded society where we have to accept that we also need to be considerate when it comes to the people around us, people that are maybe not at all charmed by the sound of a rumbling motorcycle. That is why at The Jekill and Hyde Company we offer you the possibility to adjust your sound to the moment. By doing this you can continue to carry out your favorite hobby, without disturbing others.
