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.

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. 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 in all riding modes.
A groundbreaking bike like the BMW R18 needs an exhaust that completes this bike’s potential. One of Dr. Jekill & Mr. Hyde’s most important spearheads is the rider’s possibility to choose. Not only the preferred sound mode, but also the looks and design of the exhaust.
The design of the BMW R18 differs completely from the stock exhaust, as well as the available aftermarket exhausts. The electronically adjustable exhaust system for BMW R18 comes in several different flavors. In terms of size you can choose between a long and a short version, both available in black and chrome.
For both the long as the short version we offer 4,0” end caps in different variations. To connect The Exhaust with the header set, we’ve made a custom link pipe and heat shield, available in black and chrome.
The Beat Short is a real looker. It defines itself by a slightly aggressive yet also refined look and sound. The Beat Short fits like a glove on a customized R18 in bobber style. The power of the Boxer engine is perfectly transmitted to the rumbling sound coming out of The Beat. Push the button and let the beat enchant you!
* Note: Not available for Bagger and Transcontinental models.
The Beat Long boasts a beautiful, deep rumble. For the rider that loves a smooth ride. The Beat Long suits the classic look of the R18. Push the button and the crowd will know of your arrival; never just loud, but always present. For the rider that doesn't settle for mediocrity!

Dr. Jekill & Mr. Hyde | The Exhaust offers a completely street legal, premium quality exhaust with 4 years warranty. Our 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, we’ve created a tailor made exhaust for each and every bike. By riders, for riders.
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. 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 in all riding modes.
Dr. Jekill & Mr. Hyde | The Exhaust is a completely legal exhaust system that complies with European laws and is ECE, EG-BE and TÜV approved. The reason for this is that every Dr. Jekill & Mr. Hyde system contains a smartbox: this electronic control unit is the brain of the product and contains software that reads CAN Bus signals coming from the motorcycle’s ECU.
By committing the system to the parameters set by EU legislation, the Smartbox will seamlessly and subtly intervene if necessary. Riders don’t have to worry about breaking the law in any situation; the system is always legal no matter what sound mode is selected.
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.
Our friends at Germany based WUNDERKIND-Custom have rolled up their sleeves and created a set of custom built parts for the R18, and created one of the first street legal custom BMW R18 motorcycles. It has become a true beauty and we are pleased that our Beat Short Black Exhaust fits perfectly into the design.
Other highlights are a shortened, unpainted rear fender made of steel, 3D-milled housings at the end of the struts with integrated LED indicator and tail lights, and a black comfort seat with diamond stitching and 3D mesh insert which allows a very relaxed riding style due to its shape and position.
The boys at Rabbit Ground Custom have a motto that says "A bike should not only look good, but it should make the rider happy every day." Looking at this unique take on the R18, that shouldn't be too hard.
Together with Unikatwerk they made this one of a kind BMW R18 that will make heads turn for sure and give the rider a smile from ear to ear.
LMC Lang Motorcycles really did an amazing job on this R18; creating a bobber style BMW. With an apehanger, short rear fender and more beautiful details, this is a looker for sure!
The Dr. Jekill & Mr. Hyde exhaust provides the finishing touch with the Beat Short in black. Time to start, rev and go on an adventure.
"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."
"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."
"I will never forget the moment when my 48 was brought home to me and I pressed the button for the first time. There was an incomparable, bassy sound, as it should be for a Harley. An absolute dream for every Harley rider. For me it is optically and technically by far the best system on the market and I would buy it again 100%. The look is perfect and the riding pleasure is absolutely unique. Thank you for this simply ingenious exhaust system."
"The deep rumbling sound and the estethics of the Dr. Jekill & Mr. Hyde exhausts is the «!» on this Indian beast, turning heads like no other! I am very pleased with both quality and performance, and my neighbours appreciate the gesture of silencing the roar of the engine with a touch of a button. No tuning needed what so ever, fully customized for my ride - it is simply awesome! Best exhaust system I have ever had on a bike!"
"When the sound hits you in the stomach, the ground trembles under your feet and a broad grin adorns your face, then for the first time you have pressed the button on your new Dr. Jekill & Mr Hyde exhaust system. When so many beautiful things happen to you, that's worth 5 stars plus..."
“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."
"Completely changed the game for me. My previous exhaust had a nice tone but they were just too loud - I was setting off car alarms at idle. I wasn't enjoying riding anymore. When I heard the Dr. Jekill & Mr. Hyde exhaust though, I had to have it. The tones and volume were exactly what I was looking for, a button press away from inoffensive neighborhood bike to mean and proud cruiser with a tap. This is the exhaust I wish came stock!"
"Coherent optics and robust, not intrusive sound, I am very satisfied."
"Incredibly beautiful sound! Goosebumps guaranteed, even when you start the second/third/fourth time!"
"The name really says it all: Dr. Jekill & Mr. Hyde! Apart from the great workmanship and the fantastic quality, it rounds off the entire look of my R1250GS Adventure TripleBlack perfectly. Then there is this button that turns beauty into a beast! What really impressed me is the possibility to be even quieter than a series with it. And every now and then there is this itch in the left thumb, with the subsequent grin on the face. "
"I've never regretted the decision to go with the Dr. Jekill & Mr. Hyde system and I look forward to every trip with the beautiful, deep and powerful sound. There's a night mode for those who come home late at night ;-) "
"I'm very satisfied with the exhaust! Every time I start my bike and let the deep bass sound rattle, I get goosebumps. It motivates my inner beast to get the best out of my Scout and enjoy the wonderfully pleasant and rough sound- only then I can fully enjoy a perfect motorcycle ride."
"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."
"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."
"From my point of view the best sound by far. This is exactly what a Harley-Davidson should sound like, nice and bassy. The Dr. Jekill & Mr. Hyde increases the driving pleasure by 100% and if you want to be a little gentler on the road, you always have the option to choose between the 3 levels. In addition, the quality and service are unbeatable, in my opinion the BEST system on the market. I don't want to be without them on any machine and would recommend them anytime."
"Just awesome, no comparison to the original sound. I would never go without a Jekill again."
"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. "
“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."
"Love it, great sound when open, and great that you dont wake the neighbours in the morning (unless you want to:-) Great quality, sound and instructions!"
"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."
"Just WOW! I've had a motorcycle license since I was 18, but I've never bought a bike. My dream was to buy myself a Harley by the age of 40, but it didn't quite work out. But shortly before my 41st I did. The Dr. Jekill & Mr. Hyde system simply rounds it off, it is pure riding pleasure when you are out and about in Mr. Hyde mode. That's how a Harley has to breathe. Just yesterday, I rode to a gas station, and when I came out again, my bike was being inspected by another Harley rider. I just said, can I help? His answer: just wanted to see what you're riding, it sounds mega, I got to have it. I can just say thank you! Legal with perfect sound."
"When I bought a Harley Davidson Sportster Forty-Eight, it quickly became clear to me that I had to replace the exhaust system. Of course, only one exhaust system was an option for me. The quality, optics and of course the sound of the Dr. Jekill & Mr. Hyde is simply unique on the market and all of this is still 100% legal. I would also like to highlight the great selection of end caps at this point, which allow each customer to customize. The change from the original system to the Dr. Jekill & Mr. Hyde exhaust system, transformed my Harley's sound from a lawnmower into a black beast. As soon as the infamous button is pressed, the hair on the neck stands up. Emotions and moments of happiness that Dr. Jekill & Mr. Hyde gives every motorcycle rider with their products. "
"Very good exhaust system - perfect finish and street legal. And Smartbox 2 is awesome!"
"It's just awesome I can ride my bike to work at 5 a.m., without getting into trouble with the neighbors! But when I'm on the open road, press the button on the handlebars and the valve in the muffler opens, the show begins! The best sound you can imagine, bassy, muffled, every meter I ride becomes an experience for my ears and soul! Without worrying about a traffic control! I can only recommend: get a system, it is worth every penny."
"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!”
“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?”
"I have installed my second J&H system, first on my HD Custom and since 2018 on my HD FatBob BJ 2018. What can I say, the sound is really perfect, not too loud, but also not too quiet, a bass tone, that fits the bike perfectly. I also looked and listened to other manufacturers, but then decided in favor of J&H. The advice and after sales service at J&H is great and I personally recommend all my biker friends to buy from you! The BEST! "
"In town, I use the quiet, Dr. Jekill mode. As soon as I leave the city I press the button and switch to dynamic mode, the middle position. I find this sound mode very comfortable. But if the situation asks for it, for example when drivers sticking too close to my license plate, the valve opens to the Mr. Hyde mode. And that sound impresses! With my wife on vacation, only dynamic mode is allowed. But if I am alone then..."
"The Dr. Jekill & Mr. Hyde exhaust gives your BMW R18 the sound the bike deserves. Because of this glorified sound, you get the experience that one is looking for on a cruiser. Because the sound of the exhaust can be adjusted via the electronically controlled system, you can enjoy cruising anywhere and anytime with this characteristic motorcycle."
For those interested, the BMW R 18 can be seen and heard at Motor Venray with the exhaust from Dr. Jekill & Mr. Hyde."
"I've hesitated for a long time to buy a Dr. Jekill & Mr. Hyde exhaust system. This year I finally got the heart to configure and order the exhaust system according to my wishes. After the exhaust system was mounted on my Harley-Davidson Breakout and I picked up the machine, and I was fascinated by the sound after the first 5 km. I haven't regretted my decision since. It's also a wonderful feeling not to be out on the road with an illegal exhaust system anymore. I will continue to enjoy the sound in my ears every mile. This is another reason for me never to buy an electric motorcycle, athough I am convinced that electric motorcycles also have a certain charm. But unfortunately I am a person with emotion - the sound of the motorcycle has to be top notch."
"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!"
"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!"
"The best decision I've ever made to have this mega exhaust fitted! There is simply NOTHING BETTER !!! Should be standard on every Harley - I can't get the grin off my face anymore!"
" Today was my first ride on my Road King Special with the J&H exhaust. What a revelation. It felt like a brake had come off the bike and the sound is magnificent. This is the best upgrade you can do on your bike. My bike is Euro 5 and there it still works. The sound of the Mr. Hyde mode is warm and dark. The looks are also great. This exhaust is just what you need on your bike."
"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."
"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!!"
"My Dr. Jekill & Mr. Hyde exhaust system is installed at BMW Munich. An incredibly intense sound in open mode and whisper-quiet when closed. And it looks good too."
