Purpose-built to clear the notoriously tight engine bay packaging limitations of the Torana chassis while accommodating the high-flowing exhaust port architecture of Gen III and Gen IV LS engines (such as 5.7L LS1, 6.0L L98\/L77, and 6.2L LS3 donors), this premium swap header features high-velocity 1-¾\" primary pipes stepping down smoothly into 2\" secondaries. By maximizing exhaust gas scavenging dynamics and completely bypassing restrictive factory manifolds, it unlocks elite performance, sharper throttle action, and a ferocious modern muscle car roar.\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 LS Conversion Extractor Bank Assembly\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-Duty Mild Steel Right-Hand LS Conversion Extractor Bank Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngineered specifically to facilitate the drop-in installation of GM Gen III \u0026amp; Gen IV LS-based V8 blocks into classic LH and LX Torana engine bays cleanly\u003c\/li\u003e\n\u003cli\u003eMaintains full compatibility with the starter motor mounted in its standard, factory-intended passenger-side block position—eliminating the need for expensive starter relocation kits\u003c\/li\u003e\n\u003cli\u003eHigh-flow design featuring 1-¾\" primary runners transitioning into 2\" secondary piping pathways to deliver optimal scavenging performance on modified, cammed, or high-RPM street machines\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent pathways eliminate tight bends to achieve completely smooth, uniform internal flow geometry and minimize under-bonnet heat traps\u003c\/li\u003e\n\u003cli\u003eThick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against thermal warping, face distortion, and high-pressure exhaust 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\"\u003eA415\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\"\u003eGM Holden LS V8 Small Block Engines (5.7L, 6.0L, 6.2L Gen 3 \/ Gen 4 Blocks)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003ePrimary Pipe Diameter:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e1-¾\" (44mm)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eSecondary Pipe Diameter:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e2\" (51mm)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eStarter Position Compatibility:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eStandard OEM Side Mounting Layout\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\"\u003eEngine Swap 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\"\u003e2 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 Conversion Clearance \u0026amp; Steering Geometry Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eTorana Engine Bay Constraints:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA415\u003c\/strong\u003e) is shaped explicitly around standard aftermarket conversion engine mount kits and oil pans optimized for LH-LX crossmembers.
