This is a complete system constructed from high-grade, race-proven lightweight titanium alloys. It provides an impressive increase in power across the entire rev range while also improving torque delivery. The weight is decreased by over 6 kg. The system is finished with a hand-crafted carbon-fibre hexagonal muffler – inspired by Jonathan Rea's (Kawasaki Racing Team) World Superbike–winning machine. The power level has been increased with an extra 8.2 kW (11 HP), recorded on Akrapovic’s in-house dyno with back-to-back tests of the Kawasaki with an Evolution Line (Titanium) exhaust and a Ninja ZX-10RR with a standard stock exhaust system. The exhaust delivers a unique, deep, sporty sound that enhances the system’s sporty heritage. An optional aluminium muffler bracket is available to further complement the entire system. The bike’s ECU must be remapped when the Evolution Line system is installed.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
