Give your S4 a soundtrack to match the drive.

Your S4 can do the everyday jobs and still make a favourite road feel special. This Milltek lets you choose a resonated or louder non-resonated V6 note, with valved rear silencers and a finish to suit the car. It is for right-hand-drive sport-differential cars without brace bars.

Choosing the sound

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.

Choose the finish

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.

What is included

Vehicle-specific connecting pipework, a front silencer or front silencer replacement pipes according to the chosen version, valved rear silencers, mounting brackets and the selected quad tips.

Fitment and installation

S4 B9 3.0 turbo V6 Saloon or Avant, 2016+, RHD, sport differential, no brace bars.

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.

Questions before you order

Frequently asked questions

How do I choose the right version?

S4 B9 3.0 turbo V6 Saloon or Avant, 2016+, RHD, sport differential, no brace bars. Match those details before choosing the tailpipe finish.

Which version should I choose for regular longer drives?

We would choose the resonated construction when more silencing matters to you. Engine load and other exhaust modifications still affect the sound inside the car.
