The Audi A6 C8 2.0 TFSI exhaust in detail.

The A6 C8 45 TFSI moves along with a 2.0 turbo four-cylinder producing 245 hp and 370 Nm, and a factory exhaust designed so you never hear it. The page covers 2019 to 2021 and targets the A6: our supplier documents no A7 for this engine, so your VIN is checked before manufacturing. The other C8s, from the 3.0 TFSI V6 to the S6, S7, RS6 and RS7, have separate pages.

Beneath its discretion, the TFSI keeps a character that the factory exhaust erases. With the valves open, our valved cat-back gives it a full, sporty and rewarding tone, with crisp crackles when you lift off. With the valves closed, the large saloon returns to a volume close to how it was delivered, perfect for business trips.

Nothing is welded: the system is fixed with clamps and gaskets, in about two hours, with round tailpipes. If the car has factory valves, the drive modes stay in control; otherwise, the Rog remote, whose box sits in the boot, opens and closes them at the press of a button.

The page also sells the “Manifold” option, which on this turbo engine corresponds to the downpipe carrying the catalytic converter. Chosen in 200-cell form, this downpipe leaves the A6 with full emissions control, which suits a high-mileage car; in 100-cell form, it will be accepted or not depending on the vehicle and your country’s rules, whereas its decat version, reserved for track use, makes little sense on a saloon like this. Without an ECU remap, the 245 hp stay put; it adds sound and lightens the whole a little. 304 stainless steel is the most popular material; titanium, around 40% lighter, comes in four finishes: brushed, chrome, gold or purple.

Questions about the Audi A6 C8 2.0 TFSI exhaust.

Is my A6 C8 45 TFSI Avant compatible?

Saloon or Avant, our supplier makes no distinction for the 2019 to 2021 A6 C8 2.0 TFSI. Give us your VIN when you order: we check compatibility before any manufacturing.

Does the A6 C8 45 TFSI benefit from a modified map?

For the cat-back, the 45 TFSI keeps its Audi engine management without any issue. An ECU remap becomes relevant if you add the downpipe, as it is what turns the freed-up flow into power; no Stage 2 figure is published for this version.

Can a fitted A6 C8 pass its vehicle inspection?

Present it with the valves closed: the four-cylinder regains its discretion. As long as the A6 runs with the cat-back alone or a 200-cell downpipe, nothing changes for emissions control. A 100-cell is accepted or not depending on the vehicle and your country’s rules, whereas the decat A6 only runs on the track.

For a high-mileage A6 C8, which material is best?

304 stainless steel resists salt and damp and gives a full sound. Titanium lightens the system by around 40% for the same design, sounds more metallic at high revs and does not rust.

In detail

ROG® valved exhaust system — Audi A6 C8 2.0 TFSI (2019–2021)

The A6 C8 45 TFSI moves with a 245 hp 2.0 turbo four, and a stock system drawn so you do not hear it. The ROG system replaces it with a valved system you control, without touching the engine or the ECU. Valves closed, you keep the comfortable stock sound. Open, the turbo four finally makes itself heard.

The Manifold option: what it replaces

Between the engine and our system, one stock part remains, the one that holds the catalytic converter. On this 2.0 turbo engine it is the part that smothers the most: replacing it is the only way to gain power, and only paired with a remap. Without a remap: sound, a little less weight, no power. The 200-cell sport catalytic converter retains exhaust after-treatment; the 100-cell version and the catalyst-free variant do not. No component type approval exists for these parts: check the regulations in your country before fitting.
