The Akrapovi? Slip-On Line exhaust system for the BMW S 1000 XR represents the first step in tuning and gives a great balance between price and performance. The Slip-On Line changes the nature of the bike by adding more power, removing weight, delivering improved performance and giving the machine an unmistakable Akrapovi? sound. The newly-designed exhaust muffler is shaped to fit seamlessly with the bike’s lines, making the result a beautifully crafted, eye-catching system. The outer sleeve is made of titanium, which is complemented by a carbon-fibre heat-shield and end cap, all developed out of Akrapovi?’s involvement with race-proven technology.
