10 reasons why

Dr. Jekill & Mr. Hyde gives motorcyclists the ultimate riding experience with The Exhaust: an electronically adjustable exhaust system which makes it possible to choose between three different sound modes and adjust your sound to the moment. Here are 10 reasons why you need a Dr. Jekill & Mr. Hyde exhaust.

no. 1 Awesome, unique sound

Let’s kick off with the most important one: The Exhaust offers an awesome, unique sound. Simple as that. For many motorcyclists sound is an essential and indispensable part of their hobby and passion. The ultimate way to celebrate their freedom. Dr. Jekill & Mr. Hyde’s specialized engineers have crafted a tailor-made sound for every bike, which gives riders the ultimate riding experience and can be adjusted to every situation. But you don’t have to take our word on it, the riders’ experiences speak for themselves!


How it sounds


  • Dr. Jekill Mode
  • Dynamic mode
  • Mr. Hyde Mode

no. 2 Three sound modes

A Dr. Jekill & Mr. Hyde exhaust allows the rider to choose between 3 different sound modes. 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. You can choose between a silent, mellow tone, a dynamic mid-tone or go for a deep bass sound without any treble or mid tones. 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 valve is positioned in the center of the exhaust, which gives the exhaust gases the possibility to bypass. The optimum position for sound, performance and emission and not visible from outside, which fits with our clean optic perfectly. (Note: Blackbox systems (motorcycles without CAN bus) offer two sound modes.)

no. 8 Sound engineering

Dr. Jekill & Mr. Hyde puts a lot of effort into developing the best sound. With computer simulations, the building of prototypes and extensive testing, Dr. Jekill & Mr. Hyde created a tailor made exhaust for each and every bike. Throughout the engineering process, efforts have been made to create a perfect synergy between design, performance and sound. A great example is the absorption fabric just below the body sleeve: one of the main reasons our exhausts provide a nice damping.

It filters the high and mid tones from the exhaust sound which result in the typical Dr. Jekill & Mr. Hyde character and optimal emission values. Check out the video below video for more info about the engineering process or follow the link.

no. 9 Excellent performance

The Exhaust offers the best performance and power for your motorcycle. This means that when the valve is opened an increase in performance is realized. Thanks to the design of the exhaust, there is no loss in performance while riding with a closed valve. This ensures a safe and smooth riding experience, regardless of the mode you ride in.
