Custom Exhaust Systems Tailored To You

A Dr. Jekill & Mr. Hyde exhaust allows the rider to choose between 3 different sound modes. This means that the rider can enjoy the ride with his favourite soundtrack coming from his exhaust, but also be silent and calm when this is appropriate. You can choose between a silent, mellow tone, a dynamic mid-tone or go for a deep bass sound without any treble or mid tones. With a simple push of a button, a valve in the muffler closes or opens, allowing the sound level and character to be adjusted to the moment while riding. This valve is positioned in the centre of the exhaust, which gives the exhaust gases the possibility to bypass. The optimum position for sound, performance and emission and not visible from outside, which fits with our clean optic perfectly. (Note: Blackbox systems (motorcycles without CAN bus) offer two sound modes.)

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 CANBUS 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 favourite hobby, without disturbing others.
