AKRAPOVIC S-AU/T/1H Evolution Line Exhaust System (Titanium) for AUDI RS6 Avant / RS7 Sportback Performance (C8) - OPF/GPF 2023+

Crafted from high-quality, lightweight titanium, the Evolution Line exhaust system features a specially designed layout with a single central and two side mufflers, a titanium collector from which larger-diameter stainless steel pipes than stock emerge, and custom-made flexible pipes fully insulated at their connections to the collectors. A valve on each side of the muffler controls gas flow and contributes to the system's fantastic sound. Each valve has a housing cast in Akrapovič’s own foundry, as does the complex active X-connection, which also features a valve to manage exhaust pulses from both sides of the engine. The system is finished with unique, custom-made carbon fiber/titanium tailpipes – one on each side – with an attractive design never before used. The hand-made, dynamically shaped carbon fiber outer sleeve perfectly complements the sandblasted and coated inner titanium sleeve, providing a powerful and sporty finish to this stunning exhaust system.

The system is designed to create an acoustic accompaniment that has been acoustically tuned to perfection at every rpm point to provide auditory pleasure: from a low-rpm rumble, through a powerful mid-range and a high-frequency top end with the characteristic Akrapovič racing heritage feel, all adding to the heightened excitement where every gear shift is accompanied by a sharp rumble. The system has been tuned to ensure passenger comfort for everyday driving, without unwanted drone or excessive noise. Akrapovič conducted dyno testing of the Evolution Line (Titanium) exhaust system, using an Audi RS 6 Avant Performance (C8) with a stock Audi Sport exhaust system for comparison, and achieved a power increase of 15.7 hp (m) at 6150 rpm and 17.9 Nm of torque at 6150 rpm under controlled conditions, while reducing weight by over 20% compared to the stock system.

This is an ECE-compliant system that is a serious performer in all areas. Further enhancements can be made with the addition of the optional Downpipe/Link pipe kit (SS), boosting exhaust tuning and the optional Akrapovič Sound Kit to control the valves in the exhaust and provide more flexibility in the sound the exhaust produces. To give the Evolution Line (Titanium) even more visual impact, a hand-made carbon fiber diffuser is offered as an option, in either matte or gloss finish, providing a special touch.

The Link pipe kit (SS) L-AU/SS/8/1 is a mandatory product for the Evolution Line (Titanium) S-AU/T/1H. The system is split into two codes due to packaging requirements.

If the Evolution Line exhaust system is combined with the Downpipe / Link pipe kit (SS), the Link pipe kit L-AU/SS/8/1 is not required. In this case, the ECE type approval is no longer valid, and an ECU re-map is required when it is installed. If the Akrapovič Sound Kit is installed, the ECE type approval for the Evolution Line (Titanium) exhaust system is invalid.

The ECE type approval is valid only for vehicles equipped with a gasoline particulate filter.
