The Akrapovic Racing Line system is a great balance between cost and performance. The teardrop muffler improves your bike's appearance. The conical header is 1.2mm high grade stainless, giving maximum power, maximum torque, and less weight.
 

All parts required for fitment are included (brackets/fittings/link pipe etc.) with full fitting instructions. This is developed to fit without fuel modification, and give you the unique Akrapovic racing sound. Port gaskets are not required.
