Overview

Milltek Sport catted and catless downpipes, cat pipes and front pipes for the Audi S3 2.0 TFSI quattro Sportback 8V/8V.2 (2013-2018). These parts open up the hot side of the exhaust, cut backpressure and sharpen throttle response. Pick the option that matches your exhaust: some are built to fit a Milltek cat-back, others bolt to the stock cat-back.
