Overview

Milltek Sport downpipes and front pipes, cat pipes and front pipes for the Porsche Cayman 718 GTS 2.5T (2016-2020). 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.
