Best valved exhaust for Audi A6 and A6 Avant C7 3.0 TFSI V6

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: Audi A6 / A7 / S6 / S7 / RS6 / RS7 C7 Valved Exhaust.

In the A6 C7 range, the 3.0 TFSI sat at the top of the petrol line-up, below the S6: a V6 boosted by a supercharger, always paired with quattro drive and a dual-clutch gearbox. Its instant thrust makes it a fast grand tourer, but its factory exhaust lets almost none of its character through. Let us start with the car, before talking exhaust.

The C7, from 2011 to 2018

The seventh generation of the A6, known by the code C7, arrived in Europe in early 2011 as a sedan. The A6 Avant wagon was presented in Berlin in May 2011 and went on sale in the second half of the year. Audi then renewed the car at mid-cycle: the facelift, unveiled at the Paris Motor Show in October 2014, brought the V6 more power, among other changes.

C7 production stopped in 2018, when the C8 generation took over. Our product page covers model years 2012 to 2018, before and after the facelift. If your A6 3.0 TFSI dates from 2011, send us its VIN beforehand: you will receive a written reply on the line that matches it.

Three tunes for the same V6

At its launch in the A6 C7, the V6 gives 300 hp (220 kW) and 440 Nm. From May 2012, Audi raises it to 310 hp (228 kW), reached at 5,500 rpm, with the same 440 Nm of torque, available from 2,900 rpm; the sedan then reaches 100 km/h in 5.5 seconds, with a top speed limited to 250 km/h.

With the facelift, from October 2014, the V6 goes up to 333 hp (245 kW) at 5,300 rpm, still with 440 Nm. It now needs only 5.1 seconds to reach 100 km/h. All three tunes appear on our product page, and the bars below take the values it publishes, version by version.

quattro and S tronic as standard

Whatever its tune, the A6 3.0 TFSI sends its power to all four wheels through quattro drive, and entrusts its gear changes to a seven-speed dual-clutch S tronic.

For the exhaust, neither the gearbox nor the drivetrain comes into play: sedan or Avant, 300 or 333 hp, it is the same Rog product page. The raised allroad version is not part of the product page: if that is yours, send us the VIN before ordering.

A supercharger in the heart of the V

The 3.0 TFSI does not use a turbo. Audi placed a mechanical Roots-type supercharger between the two cylinder banks, set at 90 degrees, in place of the intake manifold. Belt-driven from the crankshaft, it spins its rotors up to nearly 23,000 rpm and supplies up to 0.8 bar of pressure. Two air-to-water intercoolers, connected to a separate cooling circuit, cool the air before it enters the cylinders.

The supercharger is driven by the engine itself: pressure is there as soon as you touch the throttle, without waiting for a turbine to pick up speed. The thrust of the A6 V6 is therefore strong and even, from idle to maximum revs. The same supercharged V6 powered other Audis of the same period, such as the S4 B8, which has its own guide.

Two banks, two downpipes

On this V6, each bank of three cylinders sends its gases out through its own downpipe, and each carries its catalytic converter. Together, these two downpipes make up what is called the front part. Behind them begins the cat-back, the longest section, the one that shapes most of the sound heard outside.

On a supercharged engine, no turbine sits in the path of the exhaust gases. Nothing dampens the pulses of the V6 between the cylinders and the catalytic converter: this engine reacts very clearly to a freer exhaust.

The voice of the supercharged V6

Set free, the 3.0 TFSI has a deep, full voice at idle, which loads up with metal when the needle passes the middle of the rev counter. A V6 does not have the silky smoothness of an inline six: its sound is rougher, more present, with a touch of nervousness as the gears climb.

Audi worked on the acoustics of this engine to limit the natural whine of the supercharger. But above all it is the factory line that erases it: its bulky mufflers, drawn for a large sedan, reduce the V6 to a distant breath. At the wheel, you feel the thrust; to the ear, almost nothing tells of it.

Flaps to choose the mood

An A6 3.0 TFSI often lives two lives: during the week, motorways and appointments; at the weekend, a country road and the urge to hear the engine. A line with flaps lets it move from one to the other. Closed, the flaps force the gases through the whole muffler, and the A6 returns to a sound level close to the factory one. Open, they give the gases a direct passage, and the V6 can be heard from outside.

On the Rog line, the flaps are fitted in advance and respond to a two-button remote, with a small control box in the trunk. Once set, they keep their position, whatever driving mode is selected: nothing reopens or recloses them in your place.

Four outlets, tips and material

The Rog line of the A6 C7 3.0 TFSI ends in four round tips. Four Rog tips come with it at no extra cost, in blued titanium, gloss black or chrome; you can also do without them for a more discreet rear end.

For a sedan that drives all year, 304 stainless steel offers a full sound and resists winter salt. Titanium, about 40% lighter for the same design, makes the V6 clearer in the revs; it comes in brushed, gold or purple, with no difference between colours. That leaves the colour of the sound, also at no extra cost: the rough grain of the V6 comes through intact with the straight pipe, while the resonator dresses it in a rounder and slightly softer voice.

What the product page offers for the front

The A6 C7 3.0 TFSI product page offers, besides the cat-back, the front part under the name "Manifold": a 200-cell sport catalytic converter, which keeps the emissions control of both banks, a 100-cell sport catalytic converter, or a catalyst-free version, which is meant for the track.

With the line alone, the V6 keeps its ECU and its factory horsepower: you gain voice and a little weight. To go after power, you need the front part and a remap carried out by a tuner. Rog builds the line from your VIN, and your garage fits it, with clamps and gaskets, without welding or cutting.

How the exhaust is put together

On the A6 C7 3.0 TFSI, the Rog cat-back takes over behind the two downpipes of the V6 and runs under the body to the four round tips, with pipes, mufflers and flaps. The two downpipes, one per cylinder bank and each with its catalytic converter, make up the front part, which the product page lists, as an option, under the name "Manifold".

• Grand touring Avant

  • Stainless steel
  • 200-cell sports catalytic converter
  • Straight pipe
