The strange case of


The brand name Dr. Jekill & Mr. Hyde | The Exhaust is based on the 1886 novel “The Strange Case of Dr. Jekyll and Mr. Hyde”. It tells the tale of Dr. Henry Jekyll, a gentle and well-mannered doctor, living in Victorian London. He has a particular fascination with good and evil in human nature and starts to do various experiments. As a result he transforms into Mr. Edward Hyde; a vile and demonic persona that is the embodiment of evil.

It is only by using a special potion that he can control his horrible alter-ego and return to being Dr. Henry Jekyll. Just like the novel’s main protagonist, Dr. Jekill & Mr. Hyde exhaust systems have two (actually three) distinct personalities. But unlike in the novel, the Mr. Hyde in our exhaust systems is easily tamed; by a simple touch of a button, you can switch it on and off.



“Loud pipes save lives” is a rather clichéd slogan you hear many bikers say. Often this is used as an excuse to have an extremely noisy exhaust that hurts your ears, but like many clichés there is some truth in this saying. At The Dr. Jekill & Mr. Hyde Company they are avid motorcycle riders and they care about their own safety and the safety of our fellow riders. All bikers know that they are very vulnerable and often overlooked by cars and trucks.

When you are on the open road a Dr. Jekill & Mr. Hyde exhaust system certainly adds to your safety. You can make yourself heard and other road users will know that you are there. Can you hear Dr. Jekill & Mr. Hyde exhaust? Definitely! Does it hurt your ears? No. They have put a lot of time into the design of the sound, making it enjoyable and not annoying. In this case Dr. Jekill & Mr. Hyde would like to change the saying a bit to: “Great sounding pipes save lives!”.



Dr. Jekill & Mr. Hyde develops an electronically adjustable exhaust system that is street legal. To be 100% legal all systems have to comply with the norms and standards that are set by law. These standards apply to sound, performance and emission.

There is growing awareness about a cleaner environment and this is increasingly being implemented within legislation regarding emission. The standards have become stricter and we as a manufacturer have to comply with these regulations..

All of current Dr. Jekill & Mr. Hyde exhaust systems are set to the EURO 4 standard and have passed all emission tests flawlessly. This does not mean that they sit and wait to see what the new standards will be; their research and development department is ready for all new standards and EURO 5!
