Hear more of your S5 every time you accelerate.
The turbo V6 is a big part of why you chose your S5. This Milltek cat-back gives it a more expressive note, with a choice of resonated or louder non-resonated construction and a range of quad tailpipe finishes. These systems are for right-hand-drive, non-GPF Sportbacks without the sport differential.

Choose resonated if you want the extra silencing of a resonator, particularly for a car that spends time on longer journeys. Choose non-resonated if a louder exhaust note is your priority. The change is in the silencer layout; a titanium or carbon tip option changes the finish, not the material of the whole system.
A resonated system is the more restrained choice, but cabin sound still depends on the engine load and the other exhaust parts fitted. The resonator reduces sound but does not eliminate every low-frequency cabin note.
Polished tips make the quad outlets stand out; black blends them more closely with a dark diffuser. Brushed titanium gives a muted metallic finish, while burnt titanium adds a blue-toned accent. Choose the sound and vehicle-specific version first, then the finish you want to see on your Audi. Carbon tips add a visible carbon-fibre finish. These are tailpipe-finish choices; the exhaust body is 304L stainless steel.

S5 B9 3.0 V6 turbo Sportback, 2017+, RHD, non-GPF, without sport differential.
The sport differential, brace bars and steering side change the pipework needed under the car. Match those details to the system above. The kit is for the turbo petrol V6, not the later diesel S model. Professional fitting lets the installer align the pipes, rear silencers and tips before tightening the system.
