1. Modeswitch -The electronically controlled and adjustable system allows riders to open and close the exhaust valve with the push of a button mounted on the handlebar. The button is fully weather-resistant and flickers a red light when activated for your convenience.

2. Smartbox - The electronic control unit in our exhaust systems is the brain of our product. Thanks to its ability to read CAN bus 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. By committing the system to the parameters set by EU legislation, the Smartbox will seamlessly and subtly intervene if necessary.

3. Servomotors - By pressing the modeswitch, the Smartbox will send a signal to the servomotors. These will react and position the valve in the required mode. Thanks to a dual-cable operation the servo motors can switch back and forth between the open Mr. Hyde mode and closed Dr. Jekill mode, or engage the 50% opened Dynamic mode. The servomotors are equipped with heavy duty cables and a 100% waterproof seal to ensure strong and durable adjusters.

4. The Valve -Reacting to the servomotors our patented valve system will be positioned in the required mode, giving you the sound mode you want.

When a Dr. Jekill & Mr. Hyde® exhaust is developed for a bike, it is not just a matter of putting a muffler on and it is ready to go; their engineers have developed the perfect exhaust for your motorcycle. With computer simulations and the building of prototypes, they have created an exhaust that is tailor-made for each and every bike. With all these factors coming together in their product; a Dr. Jekill & Mr. Hyde® exhaust system has made a long journey from the drawing board to the finished product called The Exhaust. Take a look at the cross section of The Exhaust below to see what it looks like inside, the different parts it contains and the materials which are used.

When the valve is opened, the exhaust gases go straight through the exhaust, creating the deep rumble known from Mr. Hyde. When the valve is closed, the exhaust gases are diverted via the perforation to the side chambers of the exhaust, which are filled with damping. After passing through they are lead back into the exhaust and are released at the back, producing the quiet Dr. Jekill sound.

PREMIUM QUALITY

Many riders might only consider the appearance and sound, but the pipe quality is essential for your exhaust to continue performing at its peak. Therefore we take pride in the quality and durability of Jekill & Hyde products. All exhausts are made to last, designed and manufactured with longevity in mind. They need to withstand all kinds of extreme (weather) conditions and extreme heat. Therefore they are thoroughly tested, before going into production.
