"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."

"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. "

"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."

"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!!"
