Tailored specifically to fit the high-torque 3.3-Litre (200ci) and 4.1-Litre (250ci) overhead-valve inline 6-cylinder Crossflow engines, this specialized kit replaces the restrictive factory cast iron log exhaust manifold. By optimizing exhaust gas scavenging velocity and dropping engine backpressure, this mandrel-bent assembly improves low-to-mid range torque bands and throttle response while delivering a crisp, iconic inline-6 exhaust growl.\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 Heavy-Duty Mild 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\u003eEngineered specifically to match the unique cylinder port spacing and flange parameters of the classic Ford TD engine bay layout\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust gas velocity and preventing power-robbing pocket turbulence\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque bands—ideal for restoring throttle crispness, improving hill climbing capabilities, and cruise performance in street machines\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and typical classic inline-6 harmonic vibrations safely\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, warping, and high-pressure gas leaks\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\"\u003eA392S\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\"\u003eMild Steel (Standard Finish)\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 3.3L (200ci) \u0026amp; 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\"\u003eComponent Type:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003ePerformance 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 Chassis Packaging \u0026amp; Pre-Crossflow Alignment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrictly Crossflow Design:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA392S\u003c\/strong\u003e) is shaped explicitly for \u003cstrong\u003eFord Crossflow engine architectures\u003c\/strong\u003e (where the intake and exhaust configurations sit on completely opposite sides of the cylinder head block).
