Advance Headers | Mild Steel Exhaust Extractors | Holden Gemini Rodeo Jackaroo Shuttle 1.6L-2.0L | A440

PRODUCT CONTENTS:

• 1 x Heavy-Duty Mild Steel 4-Cylinder Performance Extractor Header Assembly

Key Features:

• Multi-vehicle crossover configuration explicitly designed to clear engine bay parameters across classic passenger car, light commercial van, and four-wheel-drive platforms
• Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust gas velocity and preventing power-robbing pocket turbulence
• Substantially optimizes low-to-mid range torque bands—ideal for commercial cargo transport, off-road crawling acceleration, and maintaining steady highway cruising speeds
• Heavy-duty mild steel construction structurally built to handle intense under-floor or engine bay thermal transitions and demanding continuous operating cycles safely
• Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping, face distortion, and high-pressure gas leaks
• Engineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation window of just 1 hour

⚠️ Crucial Variant Production Run & Generation Compliance Warnings:
1. Strict Year Cut-Off (Up to 1984): This product (Part No. A440) is shaped explicitly to clear engine configurations and body structures for the early Isuzu-built SOHC engine run up to 1984. It will NOT fit late-generation 4WD models optioned with newer engine families (such as 4ZE1 2.6L blocks or modern overhead-cam systems found in later model codes).
2. Downstream Connection Check: Engineered to bolt cleanly to the cylinder head ports within a fast 1-hour workshop turnaround frame. Minor variations in custom downstream intermediate pipings on older work commercial utilities may require simple alignment tracking checks during assembly setup.

Please Note: Professional installation by an exhaust specialist or qualified classic automotive mechanic is highly recommended to guarantee proper downstream system routing and a perfect leak-free seal.
