Advance Headers High-Performance Mild Steel Exhaust Extractors for Holden Rodeo & Jackaroo 2.3L Carburetted Engines with EGR
The Advance Headers Performance Exhaust Extractors (A442C) are heavy-duty tubular manifolds engineered specifically for the first and second-generation Holden Rodeo utilities and Jackaroo 4WD platforms built between 1985 and 1993. Custom-configured explicitly for the workhorse 2.3-Litre carburetted 4-cylinder engine option requiring a factory emissions loop connection, this upgrade features an integrated, pre-welded Exhaust Gas Recirculation (EGR) fitting. By replacing the highly restrictive factory cast iron log manifold, it maximizes exhaust gas scavenging velocity to unlock vital low-to-mid range working torque and crisp throttle response.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel 4-Cylinder Performance Extractor Header Assembly
- 1 x Integrated Pre-Welded Exhaust Gas Recirculation (EGR) Takeoff Port
Key Features:
- Equipped with a precision-placed, pre-welded EGR factory return thread, ensuring seamless hookup to standard carburetted emissions hardware without manual modifications
- Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and eliminating heavy factory casting restrictions
- Substantially optimizes low-to-mid range torque delivery—ideal for improving off-road crawling capability, highway overtaking, and commercial utility towing capacity
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet thermal transitions and demanding 4WD operational heat 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 exhaust leaks
- Engineered for an exceptionally fast workshop turnaround, featuring an estimated baseline installation window of just 1 hour

⚠️ Crucial Fuel System & Generation Variant Compliance Warnings:
1. Strictly Carburetted Setups: This product (Part No. A442C) is clearanced and indexed specifically around the manifold bounds of the 2.3L Carburetted 4ZD1 engine run. Please verify your fuel infrastructure prior to purchase, as this layout may conflict with later Electronic Fuel Injection (EFI) conversion components.
2. Date Run Mapping: Built to drop into the 1985–1993 KB and TF generation configurations cleanly. It will not comfortably line up with older 1.6L/2.0L blocks (up to 1984) or later updated 2.6L (4ZE1) engine bays without modification.
Please Note: Professional installation by an exhaust specialist or qualified 4WD mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
