We are proud to present you: The Carbon Steel Series by Dr. Jekill & Mr. Hyde®!

    The BMW checks all the boxes in terms of design, ergonomics and power. That’s why Dr. Jekill & Mr. Hyde® wants to make sure that you not only feel, but also hear this masterpiece of German engineering, responding to the iconic boxer punch.

     Dr. Jekill & Mr. Hyde® had created an exhaust that contains exceptional sound quality and offers three different sound modes. The Exhaust boosts a beautiful deep rumble, as well as a calm, low-key but distinctive sound.

    Make every rev count // The Sound

    Dr. Jekill Mode
    Dynamic Mode
    Mr. Hyde Mode

    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).



    Listen and enjoy the different sound modes of the Dr. Jekill & Mr. Hyde® Exhaust Systems for BMW.

    Dr. Jekill & Mr. Hyde® sound engineers have used the character of the Boxer engine as a guideline in all sound modes. We are sincerely proud of the sound and product that Dr. Jekill & Mr. Hyde® have created. The power of the engine is perfectly transmitted to the rumbling sound coming out of the Dr. Jekill & Mr. Hyde® Exhaust.  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 our showroom in Hendersonville, North Carolina. 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.



    Form follows function. That is their motto when creating The Exhaust for BMW Models. But this doesn't mean they've taken it easy. On the contrary - the result is something to be proud of and fits BMW like a glove. They chose a design that blends in perfectly with the design of the bike as a whole.

     The exhaust will be available in Carbon Steel. To complete the look we developed a stainless steel end cap. This one of a kind end cap gives the exhaust a distinguished look.

    Electronically adjustable exhaust! Adjust your sound to the moment!



    The Dr. Jekill & Mr. Hyde® 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.



    To take the BMW on a trip and you need to be prepared. A set of cases is your go-to option when you start your journey.

    That is why the new Dr. Jekill & Mr. Hyde® exhaust system for the BMW models is fully compatible with a set of cases on the bike.

    The exhaust perfectly fits, and the heat does not affect the cases. It goes without saying that this has been extensively investigated by Dr. Jekill & Mr. Hyde®'s engineers and test-riders. Time to pack up and ride!

    Dr. Jekill & Mr. Hyde® | The Exhaust offers a completely street legal, premium quality exhaust with 4 years warranty. Their exhaust system makes it possible to choose between three different sound modes on the fly, which makes every ride spectacular!

    The Exhaust is a result of German engineering and Dutch craftsmanship. With state of the art technology, perfectly crafted by the best engineers in town. With computer simulations, the building of prototypes and extensive testing, they've created a tailor made exhaust for each and every bike. By riders, for riders.

    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.


    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 Dr. Jekill & Mr. Hyde®'s 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.

    J&H on a 2023 R1250RS
    (Little Rock, AR) | July 22nd, 2023
    It goes without saying, J&H have mastered the acoustic manipulation of the exhaust note, at least for the BMW boxer engine. I bought this exhaust for a 2023 R1250RS & for the most part it does fit the bike. The only exception was I needed to remove about 3/4" or 20mm of the oem tailpipe just after the factory butterfly valve. After removing this section of the exhaust, fit up was fine. The result is just as I expected, perfect. This is my second J&H exhaust, the first one is one my 1250GSA. If you're unfamiliar or never heard the exhaust, I encourage you to find someone who has one & listen in person, the videos & audio recordings always come up short in trying to convey what it sounds like. They are a little more expensive than most other exhaust & there is a reason for that, they can... That would be the only thing I dislike about J&H, the value is there for me but everyone else that's up to to them to decide. Thanks Wunderlich, for making these products available to us in the US.
