BMW R18 with DR JEKILL and MR HYDE FULL EXHAUST!

This is what Dr Jekyll and Mr Hyde exhausts say - but this is about how to change between the quiet and loud system - Twenty five years of innovation, state-of-the art engineering and craftsmanship. Twenty five years to create the ultimate sound experience. This is it. Our love for design, eye for detail and passion for sound all comes together in The Exhaust. The electronically adjustable exhaust system makes it possible to choose between three different sound modes while riding your motorcycle. At the push of a button.
