Akrapovic Racing systems are designed for riders who demand maximum performance from their motorcycle.Systems are significantly lighter, if compared to the stock exhaust system and feature exceptional production quality, hi-tech materials and of course increased engine performance combined with pure racing sound output. The Akrapovic Racing systems were developed to complement the racing character of the S1000RR. The Racing system uses stainless steel header tubes and link pipe.

The power increase with the Akrapovic system is substantial, and can be seen from 7000 rpm right to the top of the range.  The system's effect on the torque and power curve is huge and strongest at midrange rpm. The main increase starts at around 4500 rpm and continues right into the over-rev range. All this will help you shave lap times and result in a much smoother ride.
