This updated design uses race-proven materials in the construction of the system, with a high-grade lightweight titanium link pipe, titanium inner muffler structure, and new style of end cap all matched to a carbon-fibre outer muffler sleeve, which has created an exhaust that is over 23% lighter than the standard stock version. A full and intense sound is emitted when the machine is idling, offering a deep, full tone with a distinctive Akrapovič character when on the move.The Akrapovič Slip-On Line (Carbon) exhaust upgrade is achievable through a combination of two choices of optional headers – titanium and stainless steel – which are available with an optional noise insert for those who want to combine the system with the headers. This EC/ECE-approved and Euro5-compliant product has a simple plug-and-play installation process with no remapping necessary.Installing the available optional headers invalidates the EC/ECE type-approval certificate. The EC/ECE type-approved certificate is not valid for M 1000 R model.
