The system achieves over 45% weight reduction compared to the stock exhaust. Fully compliant with ECE standards, the system is acoustically tuned to deliver a balanced and refined sound both inside and outside the vehicle. It is finished with handcrafted carbon fibre tailpipes, enhancing the overall visual appearance. Optional carbon fibre diffusers and mirror caps are available to further complement the system’s design. The optional Akrapovic Sound Kit (P-HF1194) is also available.
