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.

CLOSED - DR. JEKILL MODE

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.

OPENED - MR. HYDE MODE

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.

HALF-OPENED - DYNAMIC MODE

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