Audi S8 D5: giving the 4.0 TFSI V8 its voice back, the complete guide

The S8 D5 is the limousine for people in a hurry: 571 hp of twin-turbo V8 under the profile of an executive grand tourer. It is completely discreet in sound, and that is deliberate. But our S8 customers all share...

In detail

ROG® valved exhaust system — Audi S8 D5 4.0 TFSI V8 (2020–2024)

On the S8 D5 the 4.0 TFSI is a 571 hp twin-turbo V8, held silent by a stock system designed so nothing seeps into the cabin. 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 twin-turbo V8 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 twin-turbo V8 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.
