Constructed entirely from low-weight, high-grade titanium, it features a central muffler flanked by two valves (the housings of both valves are cast at the in-house Akrapovic foundry) and a link pipe set with an X-connection element. With unique sound patterns designed to offer maximum enjoyment, the X-connection in the link pipe section gives the exhaust system a characteristic Akrapovic high-frequency racing tone in the upper rev range, which is complemented by the deep and iconic Akrapovic rumble from low down in the rev range, providing a distinctive V8 growl. There also is a comfort mode, with no unwanted noise or drone in the cabin. Finished with eye-catching carbon-fibre \/ titanium tailpipes exiting on either side of the rear of the car, the exhaust also increases power by 5.7 kW at 6,200 rpm and adds 10.7 Nm of torque at 2,850 rpm when tested on Akrapovic's in-house dyno in back-to-back runs with RS Q8 against the stock RS Sport exhaust system. It is a plug-and-play product, and due to its ECE type approval there is no need to tune the ECU. An optional Akrapovic Sound Kit and Downpipe \/ Link pipe set (SS) is available to upgrade the Evolution Line (Titanium) exhaust. With the installation of the Downpipe \/ Link pipe set (SS), ECE type approval for the Evolution Line (Titanium) exhaust system is not valid, and remapping the ECU is mandatory when it is fitted.The Link pipe set (Titanium) CO-AU\/T\/5 is a mandatory product to the Evolution Line (Titanium) S-AU\/T\/3H. The system is split into two codes because of packaging requirements.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 gasoline particulate filter.This product fits on Audi RS Q8 Performance.\n\u003cp\u003eUpgrade the sound, performance, and appearance of your 2025 Audi RS Q8 with the Akrapovic Evolution Race Line Exhaust System, Part Number S-AU\/T\/3H. Constructed entirely from lightweight, high-grade titanium, this exhaust system combines advanced materials with Akrapovic engineering to deliver sharper throttle response, increased output, and a distinctive V8 character. The system includes a central muffler, dual valve housings cast at Akrapovic’s in-house foundry, and a link-pipe assembly featuring an X-connection element.\u003c\/p\u003e\u003cp\u003eThe X-connection produces a high-frequency racing tone through the upper rev range, while the exhaust delivers the deep Akrapovic rumble associated with the lower rev range. A comfort mode helps reduce unwanted cabin noise and drone during normal driving. Carbon-fiber and titanium tailpipes provide a premium finishing detail while exiting on both sides of the rear of the vehicle.\u003c\/p\u003e\u003cp\u003eIn back-to-back testing on Akrapovic’s in-house dynamometer against the factory RS Sport exhaust, this system increased power by 5.7 kW at 6,200 rpm and torque by 10.7 Nm at 2,850 rpm. The system is designed as a plug-and-play installation and carries ECE type approval when used in the approved configuration, so ECU tuning is not required. ECE approval applies only to vehicles equipped with a gasoline particulate filter.\u003c\/p\u003e\u003cp\u003eThe Akrapovic Link Pipe Set (Titanium), Part Number CO-AU\/T\/5, is required for installation and is sold as a separate, mandatory component because of packaging requirements. An optional Akrapovic Sound Kit and Downpipe\/Link Pipe Set (Stainless Steel) are also available. Installing the Sound Kit or Downpipe\/Link Pipe Set voids ECE type approval, and ECU remapping is mandatory when the downpipe\/link-pipe upgrade is installed.
