Hear the V6 when you ask it to work.
This non-resonated Milltek replaces the front silencer with pipework for a more prominent V6 note. Valved rear silencers and quad tips give your S4 the sound and finish that make an exhaust upgrade satisfying every time you drive it. It is for right-hand-drive cars without the sport differential.

Choose 90 mm round tips for a more restrained finish, or 100 mm round tips for a larger visual presence. The polished, black and titanium finishes let you match the contrast to your S4's diffuser and trim. Carbon and oval choices have their own shapes and references in the table. Every option here uses the same non-resonated exhaust layout.

S4 B9 3.0 turbo V6 Saloon/Avant, 2016+, RHD, 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.
