Dr. Jekill & Mr. Hyde | The Exhaust is a completely street legal system and complies with European legislation and laws. 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 on the road in all riding modes.
The smartbox; the electronic control unit in our exhaust systems is the brain of our product. Thanks to its ability to read canbus signals coming from the motorcycle’s ECU, the Smartbox makes sure you will not end up on the wrong side of the law, no matter what mode you select and will seamlessly intervene if necessary.
Developing a Dr. Jekill & Mr. Hyde | The Exhaust system is more than just putting on a muffler on a bike and go, but you probably already knew that. To determining the ultimate performance for a bike, our engineers make sure that the exhaust you have mounted on your bike is 100% legal.
But do not just take our word for it, ask the proper authorities. Before we release a system it gets thoroughly tested by them and only when they approve it, a Dr. Jekill & Mr. Hyde | The Exhaust becomes available for your bike.
