Best valved exhaust for Audi A4 and A5 B8 / B9 2.0 TFSI
For an Audi A4 or A5 with a 2.0 TFSI engine, of the B8 or B9 generation, the valved exhaust that suits is the one that finally gives the turbo four-cylinder some relief without taking away the car's touring comfort. Rog offers one exhaust per generation, a cat-back in 304 stainless steel or titanium made from your VIN, which also confirms the body style. This guide helps you place your Audi, explains what makes its 2.0 TFSI so discreet, then proposes three configurations.
Your valved exhaust for Audi A4 / A5 B8 is configured from your VIN, and the Audi A4 / A5 / S4 / S5 / RS4 / RS5 B8 / 8T Valved Exhaust page brings together every system we make for this generation.

All our exhausts for these two generations, version by version, are brought together on two pages: Audi A4 / A5 / S4 / S5 / RS4 / RS5 B8 / 8T Valved Exhaust and Audi A4 / A5 / S4 / S5 / RS4 / RS5 B9 / F5 Valved Exhaust.
This guide brings together two generations of the Audi A4 and A5 that share the same engine principle: a two-litre four-cylinder, turbocharged and with direct injection. The B8 led the way, the B9 succeeded it. Each has its own Rog product page, and your VIN decides between the two. Here is how to recognise your car and what to know before choosing.

Two generations, two product pages
The A4 B8, known by the code 8K, was launched in late 2007 as a saloon, the Avant following soon after. It was facelifted at the end of 2011, with revised lights and bumpers, and produced until 2015. The first-generation A5, code 8T, shares its platform: the coupé arrived in 2007, joined later by the five-door Sportback and by the convertible, and the range lasted until 2016.
The B9, under the code 8W for the A4, took over at the end of 2015, and the second-generation A5 followed suit. The Rog B9 product page targets the A4 and A5 2.0 TFSI of the 2017 to 2021 model years. A car from 2016 or 2017 can therefore belong to one or the other: your VIN tells us, before any manufacture.
The 2.0 TFSI versions of the B8
On the B8, the 2.0 TFSI had several states of tune. At launch, two: 180 hp with 320 Nm, and 211 hp with 350 Nm. After the facelift, the most powerful version of the A4 goes to 225 hp, still with 350 Nm, and the facelifted A5 also received a 230 hp, 350 Nm variant. The Rog B8 product page covers this range, from 180 to 230 hp.
As for the transmission, the B8 2.0 TFSI exists in front-wheel drive and quattro, with a manual or automatic gearbox depending on the version and the market: continuously variable multitronic on the front-wheel drive, seven-speed dual-clutch S tronic or tiptronic on the quattro. Neither the gearbox nor the number of driven wheels are options on the product page: your VIN is enough to confirm the exhaust.
The 2.0 TFSI versions of the B9
On the B9, the Rog product page retains two states of tune of the 2.0 TFSI: a first of 190 hp with 320 Nm, geared to economy, and a second of 252 hp with 370 Nm, the sportiest.
The A4 B9 exists as a saloon and an Avant, which receive the same exhaust. The second-generation A5 is covered too, with one nuance: the Sportback does not have the same rear as the coupé and convertible, and your VIN allows us to make the right version. If your Audi is a more recent version or carries a different state of tune from those on the product page, send us your VIN before ordering, we reply in writing.

The 2.0 TFSI, a turbo that pushes early
Under the bonnet, this 2.0 TFSI lines up four cylinders over two litres, with a single turbo and direct injection. Its strength, on an A4 or an A5, is torque available very early: the car feels lively in town and on fast roads, without having to chase the revs.
The same A4 and A5 also existed with other petrol engines, such as the naturally aspirated 3.2 FSI V6 of the B8, or those of the S4 and S5: those have their own product pages and their own guides. This one concerns only the 2.0 TFSI.
The turbo leads to the downpipe, home of the catalytic converter and first element of the exhaust. The cat-back follows, with its pipes, its silencer, its valves and its tips: it is the part that decides the sound, and the one the Rog exhaust replaces.
Why the A4 2.0 TFSI makes itself heard so little
A factory A4 or A5 2.0 TFSI is first of all a tourer: its factory exhaust was designed for calm. The turbo already absorbs part of the engine's pulsations before they reach the exhaust, and the silencer erases almost all the rest. Only a neutral hum remains, without relief, even under hard acceleration.
That is a pity, because a turbo four-cylinder has a voice of its own: more rasping and more nervous than a six-cylinder's, with a turbo whistle that accompanies every acceleration.
What a valved exhaust changes on your Audi
With the valves open, the gases avoid the silencer chambers. The 2.0 TFSI takes on a forthright grain from start-up, acceleration can finally be heard, and small crackles accompany lifting off. With the valves closed, the A4 or A5 regains the discretion of a tourer, which matters for a car used for work during the week and for holidays in summer.
On the B8 as on the B9, the valves are delivered fitted and are controlled from a two-button remote, connected to a small control unit hidden in the boot. They keep the position you give them until the next press: you decide, at the red light as on the motorway.
For the character, two choices with no price difference: the straight pipe, which lets the 2.0 TFSI speak frankly, or the resonator, which gives it a rounder and slightly softer voice, welcome in a family Avant or a convertible; the exhaust stays sporty in both cases.
Materials and tips
304 stainless steel takes winter salt in its stride and gives the 2.0 TFSI a full sound. Titanium removes about 40% of the mass for the same layout, sounds clearer in the revs, and is offered in three shades, brushed, gold or purple, at the same price.
The Rog tips are included: chrome, gloss black or blued titanium. The exhaust can also be ordered without tips. The number and position of the outlets depend on the version and the body style: your VIN allows us to respect them.
What the two product pages cover
On both product pages, the downpipe is added to the cat-back as an option, under the heading "Manifold": with a 200- or 100-cell sport catalytic converter, or catalyst-free, a version intended for the track. For everyday use, the 200-cell version is the most coherent, since it keeps emissions control.
Without the downpipe, the 2.0 TFSI keeps its programming and its factory power: only the sound evolves. More horsepower requires the downpipe and a remap, to be entrusted to a tuner. Your VIN guides the manufacture of the exhaust, which your garage then fits using clamps and gaskets, without welding or cutting.
Configure your exhaust.
How the exhaust is put together
On an A4 or A5 2.0 TFSI, B8 as B9, the Rog cat-back follows on from the downpipe and runs to the tips: pipes, silencer and valves. The front section comes down to this single downpipe, bolted to the turbo and carrying the catalytic converter, available as an option on each product page, on the "Manifold" line.
Each choice explained in detail, from sound to material: How to configure your exhaust.
Your exhaust for A4 and A5 2.0 TFSI
First choose the product page of your generation, B8 or B9, then the material, 304 stainless steel or titanium and its three shades, and the sound character, straight pipe or resonator at no extra cost. That leaves the optional downpipe, the Rog remote that controls the valves, and the Rog tips of your choice.
The price of each configuration is shown on the product page, in your currency.

Questions.
Is my A4 or A5 2.0 TFSI a B8 or a B9?
The A4 B8 was produced from 2007 to 2015, the first-generation A5 until 2016; the B9 succeeded them. For a car from 2016 or 2017, the simplest is to send us your VIN: we tell you the right product page before any manufacture.
Is my facelifted 225 hp A4 B8 covered?
Yes. The B8 product page covers the 2.0 TFSI from 180 to 230 hp, before and after the 2011 facelift, in saloon, Avant and A5. Your VIN confirms the version and the body style before manufacture.
Does my A5 Sportback B9 receive the same exhaust as the coupé?
Not quite: on the second-generation A5, the Sportback does not have the same rear as the coupé and the convertible. The B9 product page covers both cases, and your VIN tells us which one to make.
Front-wheel drive or quattro, manual or automatic: does the exhaust change?
These choices are not options on the product page. Your VIN tells us the transmission of your A4 or A5, and we check the exhaust's compatibility before making it.
Will the A4 2.0 TFSI really sound louder?
Yes: our scale from 0 to 10 places the factory exhaust of the A4 and A5 at 3, the Rog exhaust alone at 7 with the valves open, a sport catalytic downpipe at 8 or 9, and the catalyst-free version, for the track, at 10. With the valves closed, the Audi stays almost as calm as before.
Straight pipe or resonator on a touring four-cylinder?
The straight pipe keeps the rasping grain of the 2.0 TFSI, ideal for a coupé driven alone; the resonator rounds off the voice, which suits a family Avant well. Both are at the same price, and the exhaust stays sporty in both cases.
One last question about your A4 or A5?
Put it to the Rog Advisor or write to us: we reply in writing, within 24 hours.
