"A clear plus for safety!”
Werner - Berrt Travel  |   BMW GS

"Mr. Hyde position (valve open) is also ideal if I am quietly riding through traffic jams. The heavier sound is more noticeable and combined with a small speed difference it has a huge effect on the reaction of cars and trucks. A clear plus for safety!”

"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 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."

"The Exhaust gives you a real fighting mentality."
Xavier  |   BMW GS

“The Mr. Hyde mode allows me to communicate better with my motorcycle. Due to the different sound modes you get more feedback from your motorcycle, which helps, among other things, to signal when something is wrong with the motorcycle. For example when the tires have to be replaced. Mr. Hyde mode really wakes you up during a long drive or when I go off-road; it activates and motivates you. It gives you a real fighting mentality."

"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."

"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!!"

"Perfect for off road rides or near residential areas."
Nikki van der Spek - GS Trophy participant 2020  |   BMW GS

"When you close the valve then the exhaust is quiet but sounds very smooth. Perfect for off road rides in nature or near residential areas. But when you open the valve and open the throttle, then the GS has a beautiful sound. Loud but not too loud, just perfect. It has a nice and dark sound."

"The best sounding R1200 exhaust to date."

"Exquisite fit and finish, well laid out packaging and installation instructions. The adjustable exhaust sound level works flawlessly, and is very convenient to adjust to your mood and environment.

"Ride in stealth mode and not disturb anyone."
Jean - GS enthousiast  |   BMW GS

“I love to ride along the shores of Gérardmer Lake (Vosges, France). A beautiful place full of walkers, cyclists and sports enthusiasts. When I drive here I always use the Dr. Jekill mode, which gives me the possibility to ride in stealth mode and not disturb anyone. But when I make my way back on the meandering roads of Col de Bonnefontaine I switch to the Mr. Hyde mode to enjoy the delicious rumble that echoes through the mountains around me and at the same time warn oncoming traffic that I am approaching. Great right?”

"Every time I start my bike I get goosebumps."
Nick Vanhoof  |   Indian Scout

"I'm very satisfied with the exhaust! Every time I start my bike and let the deep bass sound rattle, I get goosebumps. It motivates my inner beast to get the best out of my Scout and enjoy the wonderfully pleasant and rough sound- only then I can fully enjoy a perfect motorcycle ride."

"It feels like I have 3 different exhausts."
JAAP - GS TROPHY TEAM NL  |   BMW GS

“Dust, mud, extreme weather ... I ride a BMW GS as it is meant to be! A motorcycle that breathes adventure must occasionally go off the paved road and offroad! “I used to drive with an exhaust that had only one mode, which means that there was only one sound. This was not really contributing to the driving experience. Driving with a closed valve on the paved road and opening the valve off-road really adds an extra dimension to the driving experience; it feels like I have 3 different exhausts! It is a great concept: if you show it to other people, you get a lot of positive feedback."

"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."
