Milltek Sport Cat-Back Exhaust - 2013-2018 Audi S7 Sportback 4.0T C7

This Milltek Sport cat-back exhaust fits the 2013-2018 Audi S7 Sportback (C7) with the 4.0 liter twin-turbo V8. Milltek offers the 4.0 TFSI V8 a full menu: non-resonated or resonated, with or without ValveSonic valves, and polished, black or titanium tips. Each system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Compared with the factory steel parts it is lighter, flows more freely and gives the engine a clearer, stronger voice under load, without the harsh highway drone of a cheap straight pipe. The Audi S7 C7 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. It bolts on with the factory hangers and clamps, with no cutting or welding needed. It swaps the factory exhaust from the catalytic converters back, using 70 mm (2.76 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the Sound. Non-Resonated (Louder) drops the resonator for a louder, rawer note. Resonated (Quieter) keeps a resonator for a deeper tone with less drone when cruising. Non-Resonated, Valved drops the resonator for a louder, rawer note; valves that keep the factory quiet and loud modes. Resonated, Valved keeps a resonator for a deeper tone with less drone when cruising; valves that keep the factory quiet and loud modes.

Then pick an Exhaust Tip Finish: Polished (bright polished stainless), Brushed Titanium (a brushed titanium finish), Cerakote Black (a black Cerakote ceramic coating). The finish changes the look only, not the sound.

Valve Remote: choose Add Valve Remote to include the Milltek Active Valve Control remote, a plug-and-play module that lets you open and close the exhaust valves yourself. It is only offered on systems that keep valves.

Fitment Notes

• Fits the 2013-2018 US-market Audi S7 Sportback (C7). Milltek lists the same systems for the S6 sedan, which has its own page.
• Valved systems use Milltek ValveSonic rear silencers. The optional valve remote works only with the valved systems, so it is offered with those.
