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.
Euro 5 compliance
To make the electronically adjustable exhausts Euro 5 approved for 2 in 2 Softail models with OEM-headers (except Fat Bob 114) they have developed a mandatory extender for the placing of the lambda probe. This extender is placed between the body and the end cap. This solution is an important upgrade which guarantees Euro 5 compliance.
The different electronic control units in our exhaust systems
are the brains of our product.
The different electronic control units in our exhaust systems are the brains of our product.
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.
Smartbox
The electronic control unit in our exhaust systems is the brain of our product. Thanks to its ability to read CAN bus signals from the engine's ECU, it starts the system together with the engine and goes into standby after the engine is switched off.
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.
The Valve
Reacting to the servomotors our patented valve system will be positioned in the required mode, giving you the sound mode you want.
