Jekill and Hyde

The Jekill and Hyde Company gives motorcyclists the ultimate riding experience with The Exhaust: an electronically adjustable exhaust system which makes it possible to choose between different sound modes on the fly.

By a simple push of a button a valve inside the muffler closes, opens, or opens halfway, giving your exhaust more power and performance.

Our software is programmed to intervene subtly and almost imperceptibly when the parameters set by the legislation are reached. This ensures that you are 100% legal in all riding modes.



Dr. Jekill & Mr. Hyde | The Exhaust is a completely street legal system and complies with European legislation and laws, as well as being EC/ECE/EG/ABE/ EEC/EU/ECE/EGBE and TÜV tested. We care deeply about the environment, so all of our exhaust systems are built to achieve air quality standards.


The Jekill mode is designed to blend in with your environment and become one with your surroundings. Perfect for long journeys and travelling through crowded areas.



When your surroundings allow it, you can unleash Mr. Hyde and give your bike maximum performance. Feel the power of your bike and set free your inner beast. Experience a sensation that no stock exhaust can offer you.


The mode in between Dr. Jekill and Mr. Hyde. Close to a stock exhaust but much more distinct.

the-switch When you start your bike the valve is always closed. When you push the button on your handlebars once, the valve will open up completely and your exhaust is set in the performance mode. Click it again and the valve fully closes again. When you double click the button, the valve will be opened to 50% and you ride in the dynamic mode*.

*For riders with a blackbox the mode is determined by how long you push the button.


Jekill & Hyde will be the only provider of electronically adjustable exhaust systems delivering our exhaust systems with a standard 4 year warranty, starting January 1st 2020.


All the systems and products are thoroughly tested, before going into production. Only when they pass all tests, where they are subjected to the harshest (weather) conditions and extreme heat, our products become available to the public. 

With this in mind, it was only a logical step to upgrade the standard warranty to 4 years!
