With computer simulations, the building of prototypes and extensive testing, we’ve created a tailor made exhaust for each and every bike. By riders, for riders.
Our systems are 100% street legal and have a European Type Approval, as well as being CARB/EPA and TUV tested. Our products are a result of German engineering and Dutch craftsmanship. Our exhaust systems are fully compliant with the latest EURO norm. We care deeply about the environment, so all of our exhaust systems are built to achieve air quality standards.
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 street 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.
The Sound – The Exhaust
When you ride in Mr. Hyde mode, the valve opens and you do not only feel the increase in power, you also hear it. As a company we find it necessary that this sound is not ‘loud and annoying’. Our specialized engineers have crafted a tailor-made sound for every bike that on the one hand gives riders the ultimate riding experience, but on the other hand is not a nuisance to others.
By making sure the increase in power is accompanied with a deep bass sound without any treble or mid tones. Dr. Jekill & Mr. Hyde | The Exhaust provides you with a complete product that combines the best elements of performance, design and sound quality.
