THE THREE SOUND MODES

Jekill & Hyde exhaust systems embody three different “personalities”: the Dr. Jekill mode, the Dynamic mode, and the Mr. Hyde mode. With a simple push of a button, a valve inside the muffler opens or closes, giving the exhaust more power and sound. Depending on the situation, the appropriate mode can be chosen. All modes are 100% legal.

* Blackbox systems (motorcycles without CAN bus) have two sound modes.

PREMIUM QUALITY

Quality is one of the most important core values of Dr. Jekill & Mr. Hyde. All exhaust systems are designed and manufactured for durability. They must withstand all types of extreme (weather) conditions and extreme heat. Therefore, they are thoroughly tested before production begins. If all tests are passed, only the highest quality materials, all sourced from trusted suppliers in Europe, are used for production. No compromises are made in terms of quality.

4 YEARS WARRANTY

Dr. Jekill & Mr. Hyde supplies all exhaust systems with a standard warranty of 4 years. This reflects the great confidence in the workmanship of our exhaust systems.

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 each 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 binding the system to the parameters set out in EU legislation, the Smartbox intervenes smoothly and subtly when necessary. Riders never have to worry about breaking the law. The system is always legal, no matter which sound mode is selected.

Besides, we must also understand that we live in a crowded society where we must accept that we also need to be considerate of the people around us who might not like the sound at all. That’s why at The Jekill and Hyde Company we offer the ability to adjust your sound to the moment. This way, we can continue our favourite hobby without disturbing others.
