TRIUMPH x DR. JEKILL & MR. HYDE

Dr. Jekill & Mr. Hyde offers an electronically adjustable exhaust system for Triumph 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.

<strong>STREET LEGAL, </strong>SOCIAL SOUND

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.

THREE SOUND MODES

DR. JEKILL MODE

Dr. Jekill & Mr. Hyde systems embody three distinct personalities: the Dr. Jekill mode, the Dynamic mode and the Mr. Hyde mode. By a simple push of a button a valve inside the muffler closes, opens, or opens halfway, giving your exhaust more power and sound. This gives you all the tools to adjust your sound to the moment.

Our software is programmed to intervene subtly and almost imperceptibly when the parameters set by the legislation are reached. This ensures that you are street legal in all riding modes.
