"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."
"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!"
"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!"
"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."
"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."
I love to ride along the shores of rardmer 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?"
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."
"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."
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."
"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. "
"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!"
"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 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 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 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!"
"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 ;-) "
"Incredibly beautiful sound! Goosebumps guaranteed, even when you start the second/third/fourth time!"
"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..."
"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."
"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! "
"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."
"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."
"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!!"
"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."
"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!"
"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."
"Just awesome, no comparison to the original sound. I would never go without a Jekill again."
"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."
"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. "
"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."
