Purpose-built to clear the structural parameters of first-generation 1964–1973 Ford Mustang engine bays configured with left-hand steering layouts, this kit accommodates the traditional exhaust port architecture of small-block Ford 289-Cubic Inch and 302-Cubic Inch Windsor V8 engines (including 1962–1965 early block castings). By replacing highly restrictive factory cast iron manifolds, this mandrel-bent assembly drastically reduces engine backpressure to maximize gas scavenging velocity, unlocking noticeable low-to-mid range torque, crisp throttle response, and a timeless muscle car sound.\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 Left-Hand Windsor V8 LHD Extractor Header Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Right-Hand Windsor V8 LHD Extractor Header Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngineered explicitly for left-hand drive steering geometries, providing perfect clearance around LHD steering columns, boxes, and linkages without component binding\u003c\/li\u003e\n\u003cli\u003eCustom clearance-mapped around the unique packaging constraints of factory automatic transmission bellhousings and oil pans\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and eliminating heavy factory casting restrictions\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and high-vibration muscle car applications safely\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping and high-pressure exhaust 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\"\u003eA55L\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 Small Block Windsor V8 (289ci \u0026amp; 302ci Blocks \/ 1962–1965 Castings Included)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eSteering Configuration:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eLeft-Hand Drive (LHD) Models Only\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eTransmission Compatibility:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eAutomatic Transmission Models 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\"\u003eClassic Muscle 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\"\u003e3 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 Heads)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Drivetrain \u0026amp; Steering Format Compatibility Exclusions:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eStrictly Automatic Transmissions Only:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA55L\u003c\/strong\u003e) is designed and space-mapped exclusively around underbody automatic transmission casings.
