Milltek OPF Back Exhaust System for Porsche 718 Cayman GT4 | Boxster GTS (4.0) Pre Feb 2020

Unlock the flat-six potential of your Porsche 718 Cayman GT4 or Boxster GTS (4.0L, Pre-February 2020) with this Milltek Sport OPF-Back Exhaust System. Purpose-designed for the OPF-equipped (pre-facelift) version of the 4.0L naturally aspirated models, this system replaces the OPF-back section with free-flowing 304L stainless steel pipework — delivering a more characterful, louder exhaust note whilst retaining the factory OPF for emissions compliance.

Available in five distinct tip finish options across three finish families. Designed as a bolt-on OEM replacement — no cutting or welding required. Manufactured in the UK by Milltek Sport.
