Premium quality

only the best is good enoughPremium quality materials

Quality is one of our most important core values. Dr. Jekill & Mr. Hyde | The Exhaust does not only look and sound great, it also needs to be a reliable and high quality product. On this page you will find out which different parts make our exhaust system the best on the market.

All our exhaust systems 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.

Dr. Jekill & Mr. Hyde | The Exhaust offers a street legal, beautifully designed exhaust. This is a result of German engineering and Dutch craftsmanship with state of the art technology, perfectly crafted by the best engineers in town. 

Integrated switch

Our electronically controlled and adjustable system allows riders to open and close the exhaust valve with a push of a button. Choosing Dr. Jekill & Mr. Hyde means choosing for the best quality. Every Dr. Jekill & Mr. Hyde exhaust system has an integrated switch in a high quality clutch housing, with an optimal fit between all other components on the handlebars. Also the colour of the button integrates perfectly. This way it looks like it's part of the original setup. The button is fully weather-resistant and flickers a red light when activated for your convenience.

Solid valve

The valve is the heart of our product and makes our exhaust system truly unique. Thanks to the valve, our exhaust systems are electronically adjustable in three positions. We strive for the best riding experience, so the valve must always function optimally in every situation. One of the main reasons we can achieve is that we use a solid valve.

Our valve is milled from a block, pure solid metal. This prevents the valve from deforming and it absorbs the vibrations, giving you a stable and better sounding product. The valve housing is double layered with a ball joint, because during the heating phase while riding you want to keep the resistance as low as possible at all stages.

Dr. Jekill & Mr. Hyde is the only exhaust manufacturer with a valve that is fully sealed. The valve is chemically nickel-plated and therefore enters the pores of the steel, thereby boosting the hardening and protects against corrosion. The valve is welded in the middle, which gives the exhaust gases the possibility to bypass. The optimum position for sound, performance and emission and not visible from outside, which fits with our clean optic perfectly.

Premium Absorption Fabric

Every Dr. Jekill & Mr. Hyde’s exhaust system contains premium absorption fabric just below the body sleeve. Our glass wool is heat resistant up to 800 degrees. We do not work with loose fibers, but with one single thread. With this we guarantee an optimal lifespan. The thread is held in place by a temperature blanket, also used by NASA for the space shuttle. This blanket prevents the temperature from being passed on to the body. As a result, no discoloration occurs.

The absorption fabric is one of the main reasons our exhausts provide a nice damping; it filters the high and mid tones from the exhaust sound which result in the typical Dr. Jekill & Mr. Hyde character and optimal emission values.

on the exhaust Serial number 

Every Dr. Jekill & Mr. Hyde system is built-to-order, which makes it customer-specific and therefore unique. All our systems are assembled and checked in three different stages to ensure the high standards we expect from our products. Than each exhaust system is then given a unique serial number. This, among other things, optimizes traceability so that your dealer can view all information about your unique exhaust system.
