Constructed with race-proven materials, the hand-crafted carbon-fibre tailpipes with titanium inner shells, sandblasted high-grade titanium muffler, and high-grade stainless-steel link pipe give the exhaust an incredible 49.6% weight saving compared to the standard stock system.Each side of the muffler contains an exhaust valve – with housings made in the Akrapovič in-house foundry – designed to tailor the sound. These valves deliver a sharp, distinctive, and well-defined tone to the powerplant and provide a difference between the car’s driving modes. When the Comfort is chosen, the exhaust serves up a relaxing note, ideal for long journeys. The tone changes in the Sport mode to offer a strong suggestion of the engine’s potential, and in the Cupra mode it rises to a rewarding sporty roar when pushed to the limit. The system also comes with a specially developed control kit, offering the passengers the full sound experience of an Akrapovič Evolution Line (Titanium) exhaust.A power gain of 7.8 kW (10.6 hp) at 2,800 rpm and a torque increase of 27.3 Nm at 2,750 rpm have been recorded when tested on the Akrapovič dyno against a Cupra Formentor VZ5 with a standard stock exhaust. No remapping is needed for the configuration, and ECE type approval is valid for cars equipped with an OPF (Otto Particulate Filter). An optional Akrapovič Sound Kit is also available. When this part is installed, the ECE type approval of the Evolution Line (Titanium) becomes invalid. ECE type approval is valid for cars equipped with an OPF (Otto Particulate Filter).
