It replaces the section of pipe housing the factory petrol particulate filter with a straight-through pipe, clearing the last major restriction left in a modern turbocharged petrol exhaust once a de-cat and remap are already in place. It's offered in non-resonated or resonated versions and versions to suit the factory or a Milltek system, so you can pick the setup that suits how the car's used.\u003c\/p\u003e\n\u003cp\u003eIt's aimed at owners already running a de-cat and a supporting remap who want to clear the final restriction in the system, not a bolt-on for a car that needs to stay road legal.\u003c\/p\u003e\n\u003cp\u003eBecause it removes the particulate filter, it's intended for off-road and competition use. A car with the GPF\/OPF removed will fail an MOT emissions test and isn't legal to use on UK roads.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e GPF\/OPF Bypass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC Approved:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRace System:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Time:\u003c\/strong\u003e approx. 1 to 1.5 hours (Milltek figure)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMade from T304L aircraft-grade stainless steel, which is anti-magnetic and resists discolouration\u003c\/li\u003e\n\u003cli\u003eMandrel-bent pipework keeps a constant diameter through every bend for unrestricted flow\u003c\/li\u003e\n\u003cli\u003eStraight-through pipe in place of the factory petrol particulate filter (off-road and competition use only)\u003c\/li\u003e\n\u003cli\u003eResonated (quieter) or non-resonated (louder) versions\u003c\/li\u003e\n\u003cli\u003eDesigned, developed and manufactured in the UK by Milltek Sport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFord Focus Mk4 ST 2.3-litre EcoBoost Estate\/Wagon\/Combi (OPF\/GPF Equipped) (2019 onwards)\u003c\/li\u003e\n\u003cli\u003eFord Focus Mk4 ST 2.3-litre EcoBoost Hatch (OPF\/GPF Equipped) (2019 onwards)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e any model, engine or body style not listed above.
