Specifically engineered for high-output applications, these headers are designed for the Holden VT Series II through VY Series I Commodore and WH to WK Series I Statesman models equipped with the 5.7 Litre LS1. Unlike standard street headers, the \"Competition Tuned\" design features massive 1⅞\" (48mm) primary pipes leading into a large 3\" (76mm) outlet, providing the high-volume exhaust flow required for heavily modified engines and supercharged applications. Proudly Australian-made and mandrel-bent, these headers ensure optimum exhaust pulse tuning and scavenging. This kit is a direct bolt-on for both manual and automatic transmissions while maintaining full clearance for essential engine accessories.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cp\u003eThis product offers the following performance features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompetition Grade:\u003c\/strong\u003e Large 1⅞\" (48mm) primary pipes designed for high-horsepower and supercharged LS1 engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Flow Outlet:\u003c\/strong\u003e Features a 3\" (76mm) outlet to minimize backpressure in performance builds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuned Design:\u003c\/strong\u003e Precision-engineered pulse-tuned lengths to maximize power and torque gains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMandrel Bent:\u003c\/strong\u003e Ensures consistent pipe diameter throughout every bend for unrestricted exhaust velocity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Engineered to clear Power Steering and Air Conditioning components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLS1 V8 Specific:\u003c\/strong\u003e Optimized for the 5.7 Litre Gen III LS1 engine across sedan, ute, and coupe bodies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"font-family: Arial, sans-serif; max-width: 100%; padding: 20px; border: 1px solid #ccc; border-radius: 5px; font-size: 14px; margin-bottom: 20px;\"\u003e\n\u003cstrong\u003eProduct Specifications for PH 5363\u003c\/strong\u003e\n\u003cdiv style=\"width: 100%; overflow-x: auto; margin-top: 10px;\"\u003e\n\u003ctable style=\"min-width: 800px; border-collapse: collapse; width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f0f0f0; border-bottom: 2px solid #333;\"\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eValue\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding: 10px 5px; text-align: left; white-space: nowrap;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003ePart #\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003ePH 5363\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eGasket\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eDSF 138\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003ePrimary Pipe\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e1⅞\" (48mm)\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eOxy Sensor\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eOutlet\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e3\" (76mm)\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #f9f9f9; font-weight: bold; white-space: nowrap;\"\u003eFitting Time\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003e3 Hrs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eP\/Steering\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eYes\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; background-color: #ffffff; font-weight: bold; white-space: nowrap;\"\u003eAir Con\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 5px; white-space: nowrap;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eImportant Notes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Extensions:\u003c\/strong\u003e This kit does NOT include Oxygen Sensor Wiring Loom Extensions.
