Which valved exhaust for an Audi S3 8V?
The Rog system for the Audi S3 8V is a valved cat-back exhaust in 304 stainless steel or titanium, built to your VIN for the EA888 2.0 TFSI with 300 to 310 hp depending on model phase. Valves open, the S3 gains the full voice the factory system filtered out; closed, it becomes a discreet compact again, and the 200-cell downpipe is offered as an option.
Sound, options and fitting in detail: our Audi S3 8V guide.
With 300 hp and 380 Nm, the S3 8V pushes the EA888 2.0 TFSI much further than the A3 it is based on. This page covers the 2015 to 2020 model years; the body style is not specified, so your VIN serves as the reference before manufacturing begins. The A3 8V, the five-cylinder RS3 8V and the S3 8Y each have their own.
A turbocharged four-cylinder does not have the aura of a five-cylinder, and the S3’s factory exhaust does not try to contradict that: it filters almost everything. With the valves open, our valved cat-back gives it a full, sporty voice, punctuated by crackles on lift-off. With the valves closed, the gases pass back through the silencer and the S3 returns to a volume close to stock, which matters for weekday journeys.
On this engine, the option called “Manifold” replaces the downpipe at the turbo outlet, where the catalytic converter sits. Three versions exist: 200 cells, which preserve emissions control; 100 cells, accepted or not depending on the car and the rules in your country; decat, reserved for track use. Fitted without a suitable map, it creates no horsepower. As for titanium, it weighs around 40% less than 304 stainless steel for the same design and dresses the S3 in brushed, gold or purple outlets.
The system ends in four round tailpipes and attaches with clamps and gaskets, without cutting or welding, leaving your mechanic about two hours of work on a lift. The valves respond to the Audi driving modes if your S3 has them from the factory, or to the Rog remote, whose unit is stored in the boot.

Questions about the Audi S3 8V 2.0 TFSI exhaust.
Which S3 8V models can take this system?
This covers the S3 8V 2.0 TFSI built from 2015 to 2020, which our page lists at 300 hp and 380 Nm. Our data does not distinguish between body styles: send us the VIN and we confirm compatibility before manufacturing. The more recent S3 8Y has its own exhaust.
Remapping the S3 8V: necessary or not?
The cat-back alone does without one, and the engine management remains Audi’s. It is with the downpipe that an ECU remap makes sense: the published Stage 2 figures for the S3 8V reach 368 hp and 483 Nm. Without one, a sport catalytic converter can bring up the engine warning light.
Audi S3 8V 2.0 TFSI with a Rog exhaust: what should you know about vehicle inspection?
With the cat-back only or the 200-cell sports catalytic converter, emissions control is retained: present the car with the valves closed. The 100-cell brings more sound and flow, and whether it is accepted at the emissions test depends on the car and local rules; the decat version is intended for track use.
Does an S3 8V need the Rog remote?
Only if your S3 has no factory valves. If it does, the exhaust connects to their control and the drive modes stay in charge. Otherwise, the two-button remote opens and closes at any time, whatever programme is selected.
Audi S3 8V 2.0 TFSI: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear silencer and the cabin stays calm at a steady speed. Our Rog exhausts are designed to avoid drone. Learn more: Why our systems stay calm on the motorway.
Audi S3 8V 2.0 TFSI: straight pipe or resonator?
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty. Learn more: Exhaust resonator: what does it do? Straight pipe or resonator, which sound to choose.
