    Dr. Jekill & Mr. Hyde® for the BMW R1250 GS & R1250 GSA or R1200 GS & R1200 GSA

    This Bolt on Ready Kit includes Everything You Need in one Package

    Includes the following Dr. Jekill & Mr. Hyde® Exhaust Components

    • Pipes: Nomad Available in Black or Pearl Grey
    • Endcaps: Hexagon Carbon Gloss
    • Electronics: Modeswitch Classic X for Smartbox
    • Heat shield: Carbon Fiber
    The ultimate, street legal, electronically adjustable exhaust that gives you the ultimate combination of sound, performance and comfort, pushing the legendary 1250cc Boxer engine of the R1250 GS and R1250 GS Adventure to the limits. With 3 sound modes, 4 year guarantee and a hard to beat price.

    There have been rumors and you may have heard about it on occasion… but now it is official: Dr. Jekill & Mr. Hyde® is launching a new and upgraded exhaust system for the BMW R 1200/1250 GS and GSA models. You can now pre-order The Nomad!

    The Nomad as you know it, has been upgraded on all fronts and does not only provide the rider with the already known advantages of Dr. Jekill & Mr. Hyde®, but it also takes them to the next level! With an amazing sound and a design that is second to none, the ‘new’ Nomad is a force to be reckoned with.

    Make every beat count!

    The Nomad has the characteristic features that you know from Dr. Jekill & Mr. Hyde®. You can adjust your sound to the moment with a simple push of a button on the handlebar. The Dr. Jekill Mode is even more silent than the original exhaust, which makes it perfect to ride in crowded areas or when you want to become one with your surroundings. Let your bike roar and feel the power of your legendary Boxer engine as soon as you unleash Mr. Hyde. Deep and rumbling, yet never ‘too much’, the Mr. Hyde mode is perfect when taking the unbeaten path. Last but now least the Nomad offers the Dynamic mode in between; present, yet still subtle, the Dynamic Mode is the ideal setting when you want to experience the power of your BMW, but still leave some room for more.

    Choose Your Adventure // 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® Nomad exhaust for BMW R1250 GS and R1250 GS Adventure.

    Dr. Jekill & Mr. Hyde®'s 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 Nomad.  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. Dr. Jekill & Mr. Hyde®'s motto when creating The Nomad for BMW GS Models. But this doesn't mean they've taken it easy. On the contrary - the result is something to be proud of and fits the R1250 GS and GSA like a glove. They chose a design that blends in perfectly with the design of the bike as a whole.

    They do not only offer to choose between sounds options, the rider can also choose design options (which of course unlike the sound you cannot switch by pushing a button). The exhaust will be available in black and Pearl Grey. To complete the look they've developed a gloss carbon end cap with an aluminum core. This one of a kind end cap gives the exhaust a distinguished look, matching BMW's own 719 line, and makes it recognizable even when cases are mounted on the bike. As a finishing touch we provide an optional carbon heat shield on the header.

    Electronically adjustable exhaust! Adjust your sound to the moment!



    The Nomad 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 GS on an adventure 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® Nomad exhaust system for the BMW adventure 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 their 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® 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.

    Great exhaust, got it installed. The sound it makes is THE SOUND!!! the reason I bought this one is to have a choice to change to "silent" mode and to be stuck with loud mode forever. Fantastic product, hope it will work long time.

    Pricey but worth every penny

    The build quality is excellent and the sound quality is amazing. It's great to be able to toggle in-between modes depending on where you are riding. Dr. Jekill mode seems to be about the same volume as stock, and Mr. Hyde is nicely louder. Both modes sound much better than the stock exhaust and put a smile on my face. The installation process is straightforward and the instructions are clear. The most demanding part of the process is the cable routing, but that just takes a little patience.
    Jekill and Hyde Nomad exhaust for BMW R1250 GSA

    I was looking for a deeper exhaust tone for my GS, and Jeff with Wunderlich America suggested this product, the Dr. Jekill and Mr. Hyde Nomad. Super fast shipping by Wunderlich America as usual, and it is very nicely packaged by the company. All parts separated, with clear, straightforward pictorial based directions. The fit and finish of all of the parts is impeccable, the best quality exhaust I have seen. I received excellent, expeditious technical support from Jeff and Eddie, with a few install questions I had. Install was very straightforward and took about 1.5 hours including bike reassembly . So now, when I start the bike, it’s in the Dr. Jekill mode, subdued and gentle. Once you hit the discreet placed button, Mr. Hyde is unleashed… with a very deep, throaty growl as the GS deserves. I highly recommend this product if your looking to have the ability to change your exhaust tone at the push of a button, all while remaining emissions compliant! Thanks Wunderlich America!

    Expensive but worth it...
    | August 5th, 2022
    The fit & finish is the best I've seen for an exhaust system & presentation/packaging is also by far the best. The installation instructions have been dumbed down to pictures, so you can glance at it & fully understand how to install the entire exhaust in seconds. That said, I wished they'd include some written guides as well. Youtube video & audio files on the internet never recreate the true sound for exhaust systems, so inevitably you have to take a leap of faith to some degree when purchasing an exhaust system. So with my review, take it for what it is... I purchased this because I wanted to hear my exhaust note while riding & in traffic, I wanted others to hear my exhaust & I wanted to drown out the engine noises as well. Just as important, I wanted it quiet when I roll in to my neighborhood at night. This fits all my requirements, is easy to cycle thru the various modes, seamlessly integrates with the bike CAN system & doesn't effect the performance negatively. It's a win for me all the way around.
