Audi S4 B6 Exhausts
The Audi S4 B6 packs a naturally aspirated 4.2 litre V8 into a compact quattro body, a combination Audi never quite repeated. Milltek offers performance exhaust systems for the S4 B6 that let that V8 breathe, from resonated cat-backs for a refined tone to non-resonated setups built for more flow and volume. Every system is engineered from T304L stainless steel and built for the emotion.
Not sure which setup suits your S4? Our System Education guide explains resonated versus non-resonated, cat-back versus turbo-back, and valved options so you can choose with confidence.
