Your ride back
When you ride in Mr. Hyde mode, the valve opens and you do not only feel the increase in power, you also hear it. As a company we find it necessary that this sound is not ‘loud and annoying’. Our specialized engineers have crafted a tailor-made sound for every bike that on the one hand gives riders the ultimate riding experience, but on the other hand is not a nuisance to others.
By making sure the increase in power is accompanied with a deep bass sound without any treble or mid tones. Dr. Jekill & Mr. Hyde | The Exhaust provides you with a complete product that combines the best elements of performance, design and sound quality.

Dr. Jekill & Mr. Hyde | The Exhaust is a completely street legal system and complies with European legislation and laws. Our software is programmed to intervene subtly and almost imperceptibly when the parameters set by the legislation are reached. This ensures that you are street legal on the road in all riding modes.
The smartbox; the electronic control unit in our exhaust systems is the brain of our product. Thanks to its ability to read canbus 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 and will seamlessly intervene if necessary.

"I have my Dr. Jekill & Mr. Hyde exhaust for one year now, 6.500 km on the 2019 Street Bob 107ci stage I with S&S teardrop intake... and VERY HAPPY! Amazing sound, deep, dark and loud, but quiet when necessary (neighbours, city center, horses or small kids around...) all this legal with certificate. This head-turing piece of art is a must-have on your bike!!"
"Very good exhaust system - perfect finish and street legal. And Smartbox 2 is awesome!"
“I love to ride along the shores of Gérardmer Lake (Vosges, France). A beautiful place full of walkers, cyclists and sports enthusiasts. When I drive here I always use the Dr. Jekill mode, which gives me the possibility to ride in stealth mode and not disturb anyone. But when I make my way back on the meandering roads of Col de Bonnefontaine I switch to the Mr. Hyde mode to enjoy the delicious rumble that echoes through the mountains around me and at the same time warn oncoming traffic that I am approaching. Great right?”
"When you close the valve then the exhaust is quiet but sounds very smooth. Perfect for off road rides in nature or near residential areas. But when you open the valve and open the throttle, then the GS has a beautiful sound. Loud but not too loud, just perfect. It has a nice and dark sound."
"Dr. Jekill & Mr. Hyde offers the unique powerful Harley sound I was looking for. Which is more bassy, but still civil enough for daily rides. Even the possibility of adjusting the valves with just a push of a button is very comfortable on longer tours. You get something for the price and it's worth it."
"Mr. Hyde position (valve open) is also ideal if I am quietly riding through traffic jams. The heavier sound is more noticeable and combined with a small speed difference it has a huge effect on the reaction of cars and trucks. A clear plus for safety!”
“The Mr. Hyde mode allows me to communicate better with my motorcycle. Due to the different sound modes you get more feedback from your motorcycle, which helps, among other things, to signal when something is wrong with the motorcycle. For example when the tires have to be replaced. Mr. Hyde mode really wakes you up during a long drive or when I go off-road; it activates and motivates you. It gives you a real fighting mentality."
"Love my Dr. Jekill & Mr. Hyde! Street legal, more power and 3 great sound modes with a push of a button. And my bike is 1,5 kg lighter too. Totally worth the investment!"
"Exquisite fit and finish, well laid out packaging and installation instructions. The adjustable exhaust sound level works flawlessly, and is very convenient to adjust to your mood and environment. The exhaust note is a nice mix of volume and bass tone. To me Exquisite fit and finish, well laid out packaging and installation instructions . The selectable exhaust noise level works flawlessly, and is very convenient to adjust to your mood and environment. The exhaust note is nice mix of volume and bass tone. To me the best sounding R1200 exhaust to date."
“Dust, mud, extreme weather ... I ride a BMW GS as it is meant to be! A motorcycle that breathes adventure must occasionally go off the paved road and offroad! “I used to drive with an exhaust that had only one mode, which means that there was only one sound. This was not really contributing to the driving experience. Driving with a closed valve on the paved road and opening the valve off-road really adds an extra dimension to the driving experience; it feels like I have 3 different exhausts! It is a great concept: if you show it to other people, you get a lot of positive feedback."
"Dr. Jekill & Mr. Hyde is the best investment in my bike so far!!! It adds 100% more driving fun. I can adjust the volume according to my needs, and at the push of a button a roaring sound and pure performance. And the best of all it's street legal. Many thanks to the Dr. Jekill & Mr. Hyde Team - great job keep it up!"
"So, What I particularly like about the Dr. Jekill & Mr. Hyde exhaust is the deep sound, the quality and that the valve is inside the silencer. I also think it's great that you can change the look of the exhaust afterwards by replacing the end caps. 100% legal and yet the full Harley sound is absolutely great, especially in Germany."
"I got to know Dr. Jekill & Mr. Hyde at a motorcycle fair. I was impressed by this exhaust system from the first moment. But after a test drive I was sold. Wonderful to drive being able to play with the sound. The fact that it is legal, but still gives a beautiful deep Harley sound was the deciding factor in choosing Dr. Jekill & Mr. Hyde and they are also beautiful under my bike, also not unimportant. My bike passed the strict RDW inspection and I can confidently cross the (German) border without worrying. "
"If you are looking for a high quality and exactly finished exhaust system which can be modified to your own style you have to choose Dr. Jekill & Mr. Hyde! On top you also get the possibility to change your sound levels easily by a push of a button."
"When I ride with my motorcycle I feel free. And when I ride with my Dr. Jekill & Mr. Hyde exhaust I feel like I'm the king of the streets. And when everybody looks at me and give me a thumbs up I know I made the right decision choosing this exhaust system."
Our exhaust 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, open or opens halfway. The rider can choose per situation whether or not he wants to ride in the Dr. Jekill mode, dynamic mode or unleash Mr. Hyde when the surroundings allow it.
