Audi A4 B9 Exhausts
The Audi A4 B9 blends everyday comfort with quattro composure and a willing 2.0 TFSI. Milltek offers performance exhaust systems for the A4 B9 that wake up its character, 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 A4? Our System Education guide explains resonated versus non-resonated, cat-back versus turbo-back, and valved options so you can choose with confidence.
