Manufactured using high-grade lightweight titanium, the Evolution Line exhaust system features a specially designed layout with one central and two side mufflers and a collector made from titanium, all leading from stainless steel link pipes with a larger diameter compared to stock and custom-made flex tubes, fully insulated where they attach to the downpipes. A valve on each side muffler controls the flow of gases and aids the fantastic sound produced by the system. Each valve has a housing cast in Akrapovic's in-house foundry, as does the complex active X-connection, which also features a valve for controlling the exhaust pulses from both sides of the engine. The system is finished with unique carbon fibre/titanium tailpipes " one on each side " with an eye-catching design that has never been used before, with the handmade dynamically shaped carbon fibre outer sleeve perfectly aligned with the sandblasted and coated titanium inner, all giving a powerful and sporty conclusion to this stunning exhaust system. Designed to supply a soundtrack that has been acoustically tuned to perfection at every rev point to give an aural delight from the low-down rumble, through a strong mid-range and onto a high frequency top end with distinctive feel of Akrapovic's racing heritage, all added to the increased excitement where every downshift is accompanied a sharp rumble. The system has been tuned to provide the occupants the comfort of driving like an everyday commuter with no unwanted drone or excessive noise. Akrapovic has conducted tests on its in-house dyno with the Evolution Line (Titanium) exhaust system, using an Audi RS 6 Avant (C8) with the stock Audi Sport exhaust system for comparison, and a power gain of 15.7 hp (m) at 6150 rpm and a torque increase of 17.9 Nm at 6150 rpm were achieved under controlled conditions and with a weight saving of over 30% against the stock system. This is an ECE compliant system that is a serious performer in all areas. Further changes can be made with the addition of the optional Downpipe / Link pipe set (SS), increased exhaust tuning, and the optional Akrapovic Sound Kit to control the valves in the exhaust and give greater flexibility in the sound the exhaust produces. To give the Evolution Line (Titanium) an even greater visual impact, a handmade carbon fibre diffuser in matte or glossy is available as an option to provide that special finish.

The Link pipe set (SS) L-AU/SS/6 is a mandatory product to the Evolution Line (Titanium) S-AU/TI/15H. The system is split into two codes because of packaging requirements.

If the Evolution Line exhaust system is combined with the Downpipe / Link pipe set (SS), the link pipe set L-AU/SS/6 is not needed. In this case, the ECE type approval is not valid anymore, and remapping the ECU is mandatory when it is fitted. With the installation of Akrapovic Sound Kit, ECE type approval for the Evolution Line (Titanium) exhaust system is not valid.

ECE type approval is only valid for cars equipped with otto/gasoline particulate filter.
