This is a complete stainless-steel exhaust system with a beautifully finished carbon-fibre muffler outer sleeve and high-grade titanium endcap. With the Racing Line, power and torque levels have been increased by an extra 8.2 Kw (11.1 HP) and 13.4 Nm, recorded on Akrapovic’s in-house dyno with back-to-back tests of the Kawasaki with a Racing Line (Titanium) exhaust and a Ninja ZX-10RR with a standard stock exhaust system. Coupled with linear delivery right across the entire rev range, it comes with a hexagonal muffler – including titanium inner parts to reduce weight – and a deep sporty sound. An option to add an aluminium muffler bracket is also available to complement the beautiful finish of this system. The bike’s ECU must be remapped when the Racing Line system is installed.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
