Advance Headers High-Performance Premium Stainless Steel Exhaust Extractors for Holden Rodeo & Jackaroo 2.6L EFI Engines
The Advance Headers Stainless Steel Performance Exhaust Extractors (A442iSS) are the premium, ultra-durable upgrade engineered explicitly for TF-generation Holden Rodeo utilities and Jackaroo 4WD platforms built between 1988 and 1999. Custom-configured for the workhorse 2.6-Litre Electronic Fuel Injection (EFI) 4-cylinder engine, this precision performance manifold is manufactured entirely from high-grade stainless steel to deliver superior structural longevity and maximum corrosion resistance. By replacing the highly restrictive factory cast iron log manifold and dropping exhaust backpressure, it optimizes gas scavenging velocity to unlock vital low-to-mid range working torque and sharper throttle response.
PRODUCT CONTENTS:
- 1 x Premium Stainless Steel 4-Cylinder Performance EFI Extractor Header Assembly
Key Features:
- High-grade stainless steel construction provides ultimate defense against under-car atmospheric moisture, beach salt rust, mud scaling, and harsh off-road thermal stress cycles
- 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
- 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 Oxygen Sensor Fitment & Installation Compliance Warnings:
1. Oxygen (O2) Sensor Modification Required: This product (Part No. A442iSS) is designed to suit multiple trim runs of the 2.6L 4ZE1 engine. For vehicle variants equipped with a factory exhaust oxygen sensor, a mounting hole must be marked and carefully drilled into the stainless steel collector assembly prior to final vehicle fitment to accommodate your standard sensor hardware.
2. Engine Block Restriction: Specifically engineered for the architecture and port patterns of the fuel-injected 2.6L block. It will not cleanly line up with early 2.3L carburetted (4ZD1) engine components or older pre-1984 2.0L blocks.
Please Note: Professional installation by an exhaust specialist or qualified 4WD mechanic is highly recommended to guarantee proper sensor positioning, downstream system alignment, and a perfect leak-free seal.
