First of all, let us reassure you: an electronically adjustable exhaust system from Dr. Jekill & Mr. Hyde is completely legal. Our exhaust system has a European type approval and thus complies with all European laws and regulations. This applies to all three sound modes and the rider does not have to worry about breaking the law in any situation; the system is always legal.

That being said, we must also understand that we live in a crowded society where we have to accept that we also need to be considerate when it comes to the people around us, people that are maybe not at all charmed by the sound of a rumbling Harley. That is why at The Jekill and Hyde Company we offer you the possibility to Adjust your sound to the moment. A Dr. Jekill & Mr. Hyde exhaust is an electronically adjustable exhaust system, which allows the rider to choose between different sound modes. With a simple push of a button, a valve in the muffler closes or opens, allowing the sound level and character to be adjusted to the moment while riding. This means that the rider can enjoy the ride with his favorite soundtrack coming from his exhaust, but also be silent and calm when this is appropriate. 

For many motorcyclists the sound is an essential and indispensable part of their hobby and passion. The ultimate way to celebrate their freedom. But we must also respect the freedom from the people around us. By adjusting the sound to the moment with Dr. Jekill & Mr. Hyde, you can continue to carry out your favorite hobby, without disturbing others.
