Fiesta ST Mk8.5 OPF removal pipe and mid-section upgrade by Cobra Sport
Unlock the soundtrack your hot hatch deserves with this high flow centre section upgrade for the 2022 onwards Ford Fiesta ST Mk8.5 1.5 EcoBoost. Designed as a direct replacement for the factory particulate filter section, this free flowing 76.2 mm (3 inch) mandrel bent pipe reduces restriction and transforms tone for a sharper, more aggressive exhaust note on track.
Crafted by Cobra Sport with precision TIG welding and premium stainless steel construction, this OPF delete section delivers OEM style fitment with motorsport grade build quality. Expect crisper throttle response and a deeper, louder soundtrack that brings out the character of the Mk8.5 ST while maintaining excellent fit and finish.

Fitment and mapping
