Audi S5 F5 3.0 TFSI V6 Valved Exhaust System (2017-2025)

The Audi S5 F5 exhaust in detail.

Under the code F5, Audi designates the second-generation S5, produced from 2017 to 2025 with a 3.0 TFSI turbo V6 rated at 354 hp and 500 Nm. Ever-present torque, flexibility, reliability: this engine was tuned for performance without ostentation. This page overlaps with the “S4 / S5 B9 3.0 TFSI V6” page, based on a detailed technical reference and limited to petrol versions from 2019 to 2023.

The S5’s factory exhaust takes this restraint to near-total silence, whereas many owners would like to be able to choose. With the valves open, our valved cat-back gives the V6 a deep, muscular voice, punctuated by crackles on the overrun; with the valves closed, the S5 becomes a discreet cruiser again, relaxing over long distances.

As with every page inherited from the old catalogue, your VIN is checked before manufacturing: it confirms the petrol engine and the body style, and tells us whether the S4 / S5 B9 page is a better fit. Fitting is done with clamps and gaskets, no welding, in about two hours, and the factory valves keep their control; otherwise, the Rog remote.

On this turbo V6, the “Manifold” option replaces the downpipe, the part that follows the turbo and contains the catalytic converter. As an everyday coupé or Sportback, the S5 benefits from the 200-cell downpipe, which preserves emissions control; the 100-cell one remains accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use. Without an ECU remap, the 354 hp stays as it is. Two materials are offered for the S5: 304 stainless steel, robust, and titanium, around 40% lighter and offered in three finishes.
