Custom-tailored for the iconic 4.1-Litre (250ci) overhead-valve inline 6-cylinder Crossflow engine optioned with a factory carburetor and underbody catalytic converter system, this premium manifold is manufactured entirely from high-grade stainless steel for elite thermal durability and corrosion resistance. Replacing the highly restrictive factory log exhaust manifold, this mandrel-bent assembly drastically drops engine backpressure, smoothing exhaust scavenging lines to maximize low-to-mid range torque and deliver a crisp, classic inline-6 exhaust note.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"feature-block\"\u003e\n\u003cdiv class=\"feature-content pb-6\"\u003e\n\u003ch3 style=\"color: #e60000; font-weight: bold;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003ePRODUCT CONTENTS:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Premium Stainless Steel 6-Cylinder Performance Crossflow Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-grade stainless steel construction provides ultimate defense against under-car atmospheric moisture, road salt rust, oil grime, and harsh engine bay thermal stress cycles\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust gas scavenging velocity and preventing power-robbing pocket turbulence\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque bands—ideal for improving throttle crispness, restoring low-end acceleration, and maintaining smooth highway cruising profiles\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure gas leaks\u003c\/li\u003e\n\u003cli\u003eEngineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation window of just 1.5 hours\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"specs\"\u003e\n\u003cul class=\"flex flex-col space-y-2 text-xs\"\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eBrand:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eAdvance Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003ePart Number:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eA492CSS\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eMaterial:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePremium High-Grade Stainless Steel Only\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEngine Suitability:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eFord 4.1L (250ci) OHV Inline 6-Cylinder Crossflow Petrol Only\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eFuel Delivery Layout:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eCarburetted (Carby) Models with Factory Catalytic Converter\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEmissions Adaptation:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eRequires E.G.R Adaptor Part Number: A492AD\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eComponent Type:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePremium Performance Exhaust Extractors \/ Headers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eEstimated Fitting Time:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e1.5 Hours\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWelding Required:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eNo (Direct Bolt-On Configuration to Cylinder Head Face)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Emissions Hardware \u0026amp; Application Variant Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eEGR Adaptor Component Requirement:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA492CSS\u003c\/strong\u003e) is designed to align with factory emissions compliance pathways on XF models. \u003cstrong\u003eTo successfully secure the factory Exhaust Gas Recirculation valve loop, you must purchase and use the dedicated E.G.R Adaptor (Part Number: A492AD)\u003c\/strong\u003e during installation.\u003cbr\u003e2. \u003cstrong\u003eFuel Layout Mapping Restriction:\u003c\/strong\u003e Mapped specifically around the unique intake plumbing, carburetor links, and single catalytic converter body clearance coordinates of the \u003cstrong\u003eCarburetted XF series run\u003c\/strong\u003e.
