This is a full stainless-steel exhaust system with a beautifully finished carbon-fibre muffler sleeve and high-grade titanium endcap. The Racing Line provides a increase in power and torque (+11,1 hp and +13,4 Nm), as measured on Akrapovi? dyno bench. Coupled with more 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 impressive 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.
