It replaces the restrictive factory downpipe with a larger-bore pipe fitted with a high-flow sports catalyst in place of the standard unit, using a less dense substrate that flows significantly better than the factory cat while still treating the exhaust gases passing through it. It's offered in 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 sits between a stock downpipe and a full de-cat: a genuine flow gain suited to a Stage 1 or Stage 2 remap, without giving up the catalyst entirely the way a de-cat pipe does.\u003c\/p\u003e\n\u003cp\u003eIn the UK, a replacement catalyst on a car first registered from 1 March 2001 needs ECE R103 type-approval to be road legal, so check the EC Approved line in the specification for the version you choose.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e Large Bore Downpipe and Hi-Flow Sports Cat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter:\u003c\/strong\u003e 76.2mm (3\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Style:\u003c\/strong\u003e 76.2\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\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\u003e76.2mm (3\") pipework\u003c\/li\u003e\n\u003cli\u003eHigh-flow sports catalyst flows better than the dense factory unit while still treating exhaust gases\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\u003cli\u003eFord Focus Mk3 RS 2.3-litre EcoBoost 4wd 5-Door Hatchback (2016-2018)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e the Ford Focus Mk3 ST 2.0-litre EcoBoost 5-Door Hatchback, which needs the \u003ca href=\"\/products\/milltek-sports-cat-downpipe-ford-focus-mk3-st-2-0-ecoboost-5dr-hatch-12-18\"\u003eMilltek Downpipe \u0026amp; Sports Cat Ford Focus Mk3 ST 2.0-litre EcoBoost 5dr Hatchback 12-18\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eSome versions: Large Bore Downpipe with 200 Cell High Flow Cat.
