Designed to reduce noise levels to make the Kawasaki Ninja H2R compliant with stringent decibel limits at some racetracks, the carbon Evolution Line exhaust system has been developed by Akrapovič with the latest sound technologies to decrease the level from 118 db to 98 db. This has been achieved without compromising performance, with mid-range power increasing over stock levels to further enhance the performance of the supercharged engine. Constructed from carbon fibre and titanium and incorporating the (r)evolutionary muffler design first used on the Slip-On Line exhaust for the Ninja H2, the Evolution Line design fits perfectly with the bike’s futuristic image. With the reduction in noise levels, the Akrapovič engineers have worked hard to coax a sound from the engine that is perfectly matched to the machine and offers even greater appeal for all to enjoy. Shock absorber bracket is mandatory for mounting the Evolution Line Carbon) - S-K10E3-HX2C on Kawasaki Ninja H2R (2017 model year on).For perfect performance, throttle response and durability special developed mapping from Dynojet is recommended.
