Our exhaust systems embody three distinct personalities: the Dr. Jekill mode, the dynamic mode and the Mr. Hyde mode. By a simple push of a button a valve inside the muffler closes, opens or opens halfway, giving your exhaust more power and performance. You can choose per situation whether you want to ride in the Dr. Jekill mode, dynamic mode or Mr. Hyde mode. It’s up to you.

"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."
"I am very satisfied."
Olav Schnier | R18
"Coherent optics and robust, not intrusive sound, I am very satisfied."
"The best sounding R1200 exhaust to date."
Derrick Creighton | BMW GS R1200
"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. The exhaust note is a nice mix of volume and bass tone. To me Exquisite fit and finish, well laid out packaging and installation instructions . The selectable exhaust noise level works flawlessly, and is very convenient to adjust to your mood and environment. The exhaust note is nice mix of volume and bass tone. To me the best sounding R1200 exhaust to date."
"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!”
"An incredibly intense sound in open mode."
Dirk Zetzsche | BMW R18
"My Dr. Jekill & Mr. Hyde exhaust system is installed at BMW Munich. An incredibly intense sound in open mode and whisper-quiet when closed. And it looks good too."
"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."
"...this button that turns beauty into a beast!"
Peter Janczik | BMW GS
"The name really says it all: Dr. Jekill & Mr. Hyde! Apart from the great workmanship and the fantastic quality, it rounds off the entire look of my R1250GS Adventure TripleBlack perfectly. Then there is this button that turns beauty into a beast! What really impressed me is the possibility to be even quieter than a series with it. And every now and then there is this itch in the left thumb, with the subsequent grin on the face. "
"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."
"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?”
"Give your BMW R18 the sound this bike deserves."
Motor Venray | BMW R18

Because the sound of the exhaust can be adjusted via the electronically controlled system, you can enjoy cruising anywhere and anytime with this characteristic motorcycle."
