Tailored exclusively for models featuring the factory round exhaust port cylinder head configurations, this heavy-duty tubular header upgrade replaces highly restrictive cast iron manifolds on the 3.5-Litre (6G74) and 3.8-Litre (6G75) SOHC 24-valve V6 powerplants. By maximizing exhaust gas scavenging velocity and significantly lowering backpressure, it unlocks noticeable low-to-mid range working torque, improves throttle response, and provides a crisp, deep engine 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 Heavy-Duty Mild 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\u003eDesigned precisely for third-generation chassis configurations with the primary catalytic converter positioned on the Left-Hand (L\/H) passenger side of the vehicle for seamless integration\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\u003eSubstantially optimizes low-to-mid range torque delivery—ideal for improving off-road crawling capability, highway overtaking, and vehicle towing performance\u003c\/li\u003e\n\u003cli\u003eHeavy-duty mild steel construction structurally built to handle intense under-bonnet thermal transitions and demanding 4WD operational heat cycles 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\u003cli\u003eBacked by a dependable 1-Year Manufacturer Warranty against structural defects for absolute peace of mind\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\"\u003eA349L\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\"\u003eMitsubishi SOHC 24V V6 Petrol (3.5L 6G74 \u0026amp; 3.8L 6G75 Round Port Head Models Only)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eCatalytic Converter Setup:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003eLeft-Hand (L\/H) Side Positioned Single Cat 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\"\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\"\u003e3 Hours\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"text-gray-500 font-semibold mr-1\"\u003eWarranty:\u003c\/span\u003e \u003cspan class=\"text-gray-700\"\u003e1 Year Manufacturer Warranty\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 Model Variant \u0026amp; Emissions Equipment Warnings:\u003c\/strong\u003e\u003cbr\u003e1. \u003cstrong\u003eTwin Catalytic Converter Exclusion:\u003c\/strong\u003e This product (Part No. \u003cstrong\u003eA349L\u003c\/strong\u003e) is designed strictly for early NM and NP setups using a single main catalytic converter on the Left-Hand side.
