Fitment notice: This system does not fit on vehicles equipped with an Otto particulate filter (OPF).This exhaust is constructed from high-grade lightweight titanium and features a central muffler that expands to produce two sets of tailpipes, with a choice of either a titanium or carbon-fibre finish designed to complement the lines of the car. Two valves on either side of the muffler control the airflow and are contained in valve housings cast in the Akrapovič in-house foundry. The Evolution Line (Titanium) will reduce overall vehicle weight while delivering extra power and torque through the whole rev range. With a specially developed and tuned sound, the system delivers a very high-frequency and aggressive tone in Sport+ mode. The sound is quiet when starting the engine and then becomes ideal for town driving and cruising, but it still has the unmistakable Akrapovič feel. An optional Akrapovič Sound Kit is available, which will increase the aural pleasure at lower revs and further supplement the sound as the revs rise, adding a thrill to the launch of the car from a standstill. Installation is plug&play, with no need to remap the ECU.For installing the slip-on system, the stock exhaust system must be cut. Please read the instructions carefully before installation.
