Features: This is a complete stainless-steel exhaust system with a beautifully finished carbon-fiber 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. The bike’s ECU must be remapped when the Racing Line system is installed.
