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, The United States, Singapore, Japan and most recently South-Africa. 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 most recently it is 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 two distinct personalities and keeps giving the motorcycle rider the ultimate riding experience.

power and performance
Dr. Jekill & Mr. Hyde | The Exhaust offers the best performance and power for your motorcycle. This means that when the valve is opened an increase in performance is realized. Thanks to the design of the exhaust, there is no loss in performance while riding with a closed valve. This ensures a safe and smooth riding experience, regardless of the mode you ride in. Note; when you tune your motorcycle, the difference between the opened or closed valve gets bigger.
* Tuning can influence the legality of the exhaust system.
