Audi S6

The Audi S6 is the sporty variant of the A6 saloon/estate, historically powered by a V8 and later a twin-turbo V6, positioned below the RS6 in the brand's performance hierarchy.

Fitting a Milltek performance exhaust to the Audi S6 means unlocking more from its engine: the sound gains character, weight drops versus the original and throttle response becomes more immediate — all in T304L stainless steel, made in England and tested at the Nürburgring.

For the Audi S6, Milltek's catalogue includes: Active Sound Control, Active Valve Control, Additional parts, Cat-back, Large Bore Downpipes and Hi-Flow Sports Cats, Large-bore Downpipes and Cat Bypass Pipes. Exhausts with road homologation state so in the product description and are delivered with the relevant certificate.

Browse the products below to find the exhaust compatible with your Audi S6. Looking for another Audi, find the full range here: All Audi models by Milltek.
