Audi S3

The Audi S3 is the sporty, quattro all-wheel-drive variant of the premium compact A3, available across several generations with a turbocharged 4-cylinder engine and steadily growing power outputs.

Fitting a Milltek performance exhaust to the Audi S3 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 S3, Milltek's catalogue includes: Additional parts, Cast Downpipe with HJS High Flow Sports Cat, Cast Downpipe with Race Cat, Cat-back, HJS Tuning ECE Downpipes, Large Bore Downpipe and Hi-Flow Sports Cat, Large-bore Downpipe and De-cat, Particulate Filter-back, Turbo-back including Hi-Flow Sports Cat. Exhausts with road homologation state so in the product description and are delivered with the relevant certificate.
