Description
This is the rear muffler section only and does not include the front down pipes or center link pipe sections that may be pictured for fitment purposes.
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 down pipes.
A valve on each side muffler controls the flow of gases and contributes to 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 fiber and titanium exhaust tips, one on each side, with an eye-catching design that has never been used before.
The exhaust tips are a combination of carbon fiber outer sleeves perfectly aligned with sandblasted and coated titanium inner tubes, all giving a powerful and aggressive look 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.
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 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.
This system gives a weight reduction 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, and the optional Akrapovič Sound Kit to control the valves in the exhaust and give greater flexibility in the sound the exhaust produces.
To give the Evolution Line an even greater visual impact, a handmade carbon fiber diffuser in matte or gloss finish is available as an option
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.
