Pacemaker Competition Tuned Headers - VT-VY Series 1 / WH-WK Series 1 5.7L LS1 Gen III V8 - PH5363 L/R VT-VY SERIES 1

Unleash maximum performance from your Gen III V8 with the Pacemaker PH 5363 Competition Tuned Headers. 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.
