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 Akrapovič’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 Akrapovič’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. Akrapovič 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 Akrapovič Sound Kit to control the valves in the exhaust and give greater flexibility in the sound the exhaust produces.
Akrapovic Sound Kit
The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.
The exhaust system requires the use of Akrapovics Link Pipes, which are not included with the main system. Optionally, Akrapovic also offers their link set in combination with their stainless steel downpipe set.
