Specially manufactured from high-grade stainless steel to deliver superior structural longevity, outstanding corrosion resistance, and a striking high-end finish under the hood, this kit perfectly fits the VT Series I engine bay parameters. By completely replacing the highly restrictive factory cast iron log manifolds, it dramatically lowers backpressure, optimizes exhaust gas scavenging velocity, and provides an aggressive, crisp V8 tone.\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 Performance Exhaust Extractor Header Set (Left \u0026amp; Right Bank 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 maximum defense against under-car atmospheric moisture rust, extreme gas scaling, and harsh environmental oxidation\u003c\/li\u003e\n\u003cli\u003eTuned mandrel-bent primary piping pathways map perfectly to high-port symmetrical Holden EFI cylinder heads, ensuring completely uniform gas flow routing and maximizing engine efficiency\u003c\/li\u003e\n\u003cli\u003eSubstantially optimizes low-to-mid range torque delivery and throttle response—perfect for high-performance street cruisers, heavy towing setups, and customized show cars\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 exhaust gas leaks\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on replacement path engineered specifically to route cleanly down past the updated VT K-frame profiles, automatic transmission casings, and steering gear layouts cleanly\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\"\u003eA315SS\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\"\u003eHigh-Grade Stainless Steel\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\"\u003eHolden 5.0L 304ci\/308ci EFI Pushrod V8 Petrol Only (VT Series I Iron Block Only)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eDrivetrain Profile:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eRear-Wheel Drive (RWD) Models\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\"\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 Head)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Crucial Engine Family Fitment Warning:\u003c\/strong\u003e\u003cbr\u003eThis product (Part No. \u003cstrong\u003eA315SS\u003c\/strong\u003e) is configured explicitly for the traditional Australian \u003cstrong\u003e5.0L Holden V8 iron block engine\u003c\/strong\u003e utilized strictly in the \u003cstrong\u003eVT Series I\u003c\/strong\u003e production run between 1997 and 1999.
