"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!!"

"Legal, but still a beautiful deep Harley sound."
Harley Dutchies  |   Harley-Davidson Sportster

"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. "

"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."

" 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."

"The unique powerful sound I was looking for."
@dysnrider  |   Harley-Davidson Sportster

"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."

"Legal with perfect sound."
Sascha Koerner  |   Harley-Davidson Fat Boy

"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."

"This is exactly what a Harley-Davidson should sound like!"
Alessandro Silverfox  |   Harley-Davidson Sportster Iron 1200

"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."

"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."

"100% legal and yet the full Harley sound."
@strandfahrer  |   Harley-Davidson Street Bob

"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."

"Dr. Jekill & Mr. Hyde makes the hair on the neck stand up."
Sportster Forty-Eight Icon  |   Harley-Davidson Sportster

"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 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! "

"I am a person with emotion - the sound of the motorcycle has to be top notch."
Frank Schelper  |   Harley-Davidson Breakout

"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."
