Best valved exhaust for Audi A3 8Y 2.0 TFSI

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: Audi RS3 8Y / S3 8Y / A3 8Y exhaust system.

The A3 8Y is the fourth generation of Audi's compact. In 40 TFSI quattro form, it pairs a two-litre turbo with all-wheel drive: enough to deliver punchy acceleration in a compact, well-finished car. Its factory exhaust, for its part, was designed above all so that you would not hear it. Before choosing, let us go around your A3.

The fourth A3

Audi unveiled the 8Y-generation A3 Sportback in March 2020, with first deliveries in spring. The saloon, with the profile of a four-door coupé, was unveiled as early as April 2020. This generation rests on the same technical base as the Golf 8 and adopts a fully digital cabin, but it keeps what has made the A3 what it is from the start: a compact with easy dimensions, carefully finished, as comfortable in town as on the holiday road.

At launch, the range included only front-wheel-drive engines; the quattro versions arrived afterwards, over the months. The 40 TFSI quattro, with the two-litre engine, is one of these additions. It is the one our product page targets, for the 2021 to 2024 model years.

The facelift, presented in March 2024, touched up the compact's styling and equipment. A 204 hp 40 TFSI quattro has since appeared in the catalogue: for an A3 of this type, send us the VIN first, and the reply reaches you in writing with what we can make for it.

The 40 TFSI quattro and its 190 hp

In the A3 40 TFSI, the 2.0 TFSI lines up four cylinders for 1,984 cc, with direct injection and a turbocharger. It delivers 190 hp, or 140 kW, from 4,200 to 6,000 rpm, and above all 320 Nm from 1,500 rpm, held up to 4,100 rpm. This early torque gives the compact vigorous pick-up in the intermediate gears, without having to go looking for high revs.

This engine belongs to the EA888 family, found under many bonnets in the group in various tunes. In the A3, it occupies a place of its own: enough power to make the 40 TFSI quattro a quick compact, enough restraint to remain an everyday car.

Just below, two bars compare the factory figures of the A3 40 TFSI with those published on our product page.

Stage 2: published figures with the front section and an ECU remap carried out by a tuner.

quattro drivetrain and S tronic gearbox

On the 40 TFSI, the 320 Nm pass through the S tronic, a gearbox with two clutches and seven speeds, then through the quattro drivetrain. On a transverse-engined compact like the A3, the front axle is driven permanently and an electronically controlled clutch sends torque to the rear as soon as grip or driving demand it. On a wet road or coming out of a tight bend, this is what lets you use that torque without wheelspin.

For the exhaust, the all-wheel drive has a simple consequence: a short driveshaft under the floor, and the exhaust has to work around it. Your VIN gives us the exact version of your A3, and it is from this that we make the exhaust.

Downpipe and cat-back on the 2.0 TFSI

Under the A3, the two-litre's exhaust divides into two sections. The first, the downpipe, descends from the turbo and houses the catalytic converter: we call it the front section. The second, the cat-back, takes over to reach the rear bumper with pipes, silencer and, at Rog, valves.

The cat-back does most of the sound. The downpipe works mainly on the engine's breathing: on a turbo four-cylinder, it is the most marked restriction after the silencer, and by replacing it, then remapping the engine, a tuner can release power.

A voice bigger than the car

A well-freed turbo two-litre has a character you would not suspect when listening to a factory A3: a rasping grain at idle, a sound that thickens as soon as the turbo builds boost, and a clean climb in revs up to 6,000 rpm.

With the Rog exhaust, valves open, the A3 takes on a broad, sporty voice, deeper than its displacement would suggest, and lets the exhaust crackle when you lift your foot. The aim is not to make noise for its own sake: it is to give the compact a sound that matches its performance, at start-up as through a string of bends.

What makes the factory A3 so well-behaved

Audi tuned the A3's exhaust for the comfort of its occupants and for noise regulations: bulky silencers, neutral sound, and an engine you barely hear, even when it is working. For a premium compact, it is a logical choice, but it deprives the 40 TFSI quattro of part of its character.

A valved exhaust lets you have both. Closed, the valves force the gases through the full detour of the silencer: the A3 stays roughly as calm as on delivery, for coming home late without waking the neighbourhood or driving a long way on the motorway. Open, they free a direct passage, and the four-cylinder makes itself heard.

The Rog remote

For your A3, we deliver the exhaust fitted with our valves, a small remote and a control unit to stow in the boot. Two buttons are enough: one to open, one to close, and the chosen position holds until your next press, whatever driving profile the car displays.

On a compact that serves equally well for daily journeys and weekend outings, this freedom is precious: you decide the A3's voice at the moment you want, without digging through the vehicle's settings.

Straight pipe or resonator

Two characters are offered for the A3, with no difference in price. With the straight pipe, the 2.0 TFSI keeps its rasping timbre and its crackles intact. With the resonator, it takes on a rounder and slightly softer voice: on a compact that does a lot of town driving or often carries passengers, it is a pleasant setting, and the exhaust remains decidedly sporty.

Front section, material and fitting

Upstream, the product page also sells the A3's downpipe, filed under the "Manifold" label. Three versions exist: catalysed with 200 cells, factory emissions control remains assured; catalysed with 100 cells, its acceptance depends on the car and on the rules of your country; catalyst-free, it is reserved for the track. For an A3 that is driven all week, the 200-cell is the most coherent.

With the cat-back alone, the 40 TFSI quattro keeps its 190 hp and its Audi engine management: the exhaust changes the voice, not the power. 304 stainless steel resists winter salt and gives a full sound; for the same layout, titanium is about 40% lighter, and its three shades, brushed, gold or purple, change nothing in the price.

Once the exhaust is made to the VIN of your A3, all that remains for your garage is to assemble it: clamps, gaskets, no welding and no cutting.

How the exhaust is put together

On the A3 8Y 40 TFSI quattro, the Rog exhaust starts at the end of the downpipe and runs along the floor to the rear bumper: that is the cat-back, with pipes, silencer and valves. The downpipe constitutes the front section of the exhaust; on the product page, you add it if you wish via the "Manifold" option.

Each choice explained in detail, from sound to material: How to configure your exhaust.

Three recommended configurations.

• Weekday compact

  • Stainless steel
  • No manifold
  • Resonator
  • Rog remote

  For an A3 that does the commute: Audi's front section stays put, the 2.0 TFSI gains a rounded voice, and the remote silences it before you get home.

  View this configuration

• Mountain roads in quattro

  • Brushed titanium
  • 200-cell sports catalytic converter
  • Straight pipe
  • Rog remote

  For a 40 TFSI quattro that loves hairpins: a two-litre that breathes better, a catalytic converter that stays in service, and a rasping grain that resounds on exit from the hairpin.

  View this configuration

• A3 to be tuned

  • Gold titanium
  • 100-cell sports catalytic converter
  • Straight pipe

  For an A3 that you plan to entrust to a tuner for a remap: a less restrictive downpipe, titanium to lighten it, and a gold shade that does not go unnoticed.
