Make every beat count // The R18 Sound

Dr. Jekill Mode
Dynamic Mode
Mr. Hyde Mode

Both the long and short version of The Exhaust for BMW R18 contain exceptional sound quality. Equipped with three different sound modes the exhaust boosts a beautiful, deep rumble (Mr. Hyde mode), tamed Mr. Hyde sound with a little more presence than the Dr. Jekill sound (Dynamic Mode), as well as a calm, low-key but distinctive sound (Dr. Jekill mode).

Our sound engineers have used the character of the boxer engine as a guideline in all sound modes. We are sincerely proud of our sound and product that we have created. The power of the Boxer engine is perfectly transmitted to the rumbling sound coming out of the Beat. But don't take our word for it. Listen for yourself in the video below. And if it is (again) possible, experience it live at a BMW dealer. A Dr. Jekill & Mr. Hyde exhaust is something you have to experience in real life, in order to fully appreciate the sound and truly feel it.

HOW DOES IT WORK?

TECHNOLOGY



Jekill & Hyde Exhaust contains different electronic control units to ensure the best street legal sound and ultimate performance.

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.


Adjust your sound to the moment with three sound modes

Dr. Jekill & Mr. Hyde systems embody three distinct personalities: the Dr. Jekill mode, the Dynamic mode and the Mr. Hyde mode. By a simple push of a button a valve inside the muffler closes, opens, or opens halfway, giving your exhaust more power and sound. This gives you all the tools to adjust your sound to the moment.


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 our 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.

When all the tests are passed and an exhaust becomes available to the public, only the highest quality materials are used for the production which are all sourced from trusted suppliers in Europe. Absolutely no compromises have been made on quality.
