STREET LEGAL
Dr. Jekill & Mr. Hyde | The Exhaust is a fully legal exhaust system that complies with European legislation and is ECE, EC-BE, and TÜV approved. This is because 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 intervene seamlessly and subtly when necessary. Riders never have to worry about breaking the law; the system is always legal, regardless of which sound mode is selected.
HOW IT WORKS
Our exhaust systems have three distinct personalities: the Dr. Jekill mode, the dynamic mode, and the Mr. Hyde mode. With a simple push of a button, a valve in 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 regulations are reached. This ensures that you remain 100% legal in all riding modes.
Dr. Jekill & Mr. Hyde | The Exhaust is a fully legal system that complies with European laws and regulations, carries all necessary certifications, and is TÜV approved. We care about the environment, so all our exhaust systems are designed to stay well within air quality standards.
