Back in time
Dr. Jekill & Mr. Hyde
A bit of history
Every success starts out small. Even though Dr. Jekill & Mr. Hyde is now an established brand within the motorcycle world, it was only a little more than 20 years ago that Dr. Jekill & Mr. Hyde was merely an idea.
Back in 1997 when the first Dr. Jekill & Mr. Hyde systems were created the word ‘custom-made’ was the most appropriate term to describe the products. It did not matter which bike you rode, if it was a big cruiser or a racing rocket, an exhaust would be built especially for your bike. Because of the success of these exhaust systems and a good nose for business Jacques van de Kerkhof decided he wanted to invest in The Jekill and Hyde Company, under the condition that it would be professionalized.
From custom to legal
The next step for The Jekill and Hyde Company was to build an exhaust that would be 100% legal and in compliance with European law. The engineers kept working hard on this, but never got to this point, until Jacques met Mario Müller. Mario already had a lot of experience as an engineer in the motorcycle industry. This cooperation finally resulted in the creation of an exhaust system that was 100% legal and in 2010 the European Type Approval was finally obtained. With still only 4 employees working for the company it was time to conquer the European market. The system proved to be successful, especially in countries where the law was strictly enforced regarding illegal exhaust systems, a Dr. Jekill & Mr. Hyde system was the ideal solution for all those who wanted to experience the ultimate riding feeling, without being afraid to end up on the wrong side of the law.
Branching out
After Europe the step was taken to also provide the rest of the world with Dr. Jekill & Mr. Hyde | The Exhaust. After offices were set up in Germany, Switzerland and France, the company branched out in Canada, Singapore, Japan and more. Besides exploring new markets, the palette of brands The Jekill and Hyde Company develops exhaust systems for, keeps growing. Where there was first a focus on large big twin bikes like Harley-Davidson, Indian and Victory, it also became clear that more brands could use an upgrade with the Dr. Jekill & Mr. Hyde sound. First the R-series of BMW got added to the roster and subsequently it became possible to equip your KTM with a Dr. Jekill & Mr. Hyde | The Exhaust.
A lot has happened in the short time from an idea to a well-known brand and a lot has changed, yet the main principle has always stayed the same. The Jekill and Hyde Company still produces exhaust systems with three distinct personalities and keeps giving the motorcycle rider the ultimate riding experience.

"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. "
"Perfect finish and street legal."
Martin Brunner | Harley-Davidson Fat Boy
"Very good exhaust system - perfect finish and street legal. And Smartbox 2 is awesome!"
"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."
"Choose your own style."
@marc_stone82 | Harley-Davidson Sportster Forty-Eight
"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."
"A must-have on your bike!"
Thomas Peerlinck | Harley-Davidson Streetbob
"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!!"
"Roaring sound and pure performance!"
Walter Wais | Harley-Davidson Sportster
"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!"
"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."
"I feel like I'm the king of the streets."
@mawi_davidson | Harley-Davidson Sportster Forty-Eight
"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."
