The S7 Sportback shares with the C7 S6 the 4.0 TFSI twin-turbo V8 with its turbochargers inside the V, a layout that shortens the exhaust paths and sharpens response. The body is that of the A7, a large five-door coupé with a tailgate and a rear spoiler that rises automatically at speed.
For the Audi S7 (C7) 4.0 TFSI V8 Sportback (2012-2018), Armytrix offers the cat-back system with Valvetronic silencers and downpipes. Versions without a catalyst are for track use only.
Armytrix builds its exhausts in Taiwan, in T304 stainless steel and titanium, and is one of the brands that made valved exhausts affordable: the valve sends the gases through the silencer or around it, and it is controlled with the supplied remote or a smartphone app through a module plugged into the OBD port. Armytrix exhausts are not road approved in the European Union or Switzerland: they are intended for track use.
Armytrix systems are prepared to order and the price is on request: contact us for a quote, for delivery times or if you have any doubt about compatibility with your car. All Armytrix exhausts for Audi are on their own page.
