Holden Rodeo 2.6L 4ZE1 EFI Round Port Headers 1988–1999 – Wildcat WILD006

Wildcat WILD006 exhaust headers (extractors) are designed for selected Holden Rodeo models from 1988–1999 fitted with the 2.6L 4ZE1 EFI petrol engine with round exhaust ports.

Featuring an interference-style header design, WILD006 uses 1.58" primary pipes, 1.75" secondary pipes and a 2.00" outlet. This combination is designed to improve exhaust gas flow and scavenging while maintaining good exhaust velocity, helping improve torque, throttle response and usable engine performance.

WILD006 is listed as a direct-fit application for the specified compatible 4ZE1 engine configuration.

IMPORTANT: WILD006 is specifically designed for the round-port 4ZE1 cylinder head. Check the exhaust-port configuration before ordering.

Please check availability and current lead time before ordering.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.6L 4ZE1 petrol engine theoretically draws in approximately 5,200 litres of intake air per minute and can expel around 15,600 litres of hot exhaust gas per minute at approximately 600°C.

A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

• Apply penetrating lubricant such as WD-40 or similar to the manifold studs, nuts and exhaust fasteners before removal
• Remove all traces of the old manifold gasket before installing the headers
• Inspect the cylinder-head sealing surface, manifold studs and threads before installation
• Fit a new DSF069 exhaust manifold/header gasket
• Use high-temperature exhaust gasket sealant where appropriate
• Trial-fit the headers and check exhaust alignment before fully tightening the mounting hardware
• Check clearance around the steering, suspension, transmission, starter motor and bodywork
• Protect the painted header surfaces during trial fitting and installation
• Check all exhaust connections for leaks after installation
• Inspect and re-tighten the header mounting hardware after approximately 500km to help maintain a reliable gasket seal

Warranty & Compliance

Wildcat headers are covered by the applicable 2-year manufacturer's warranty subject to standard warranty terms and conditions.

Installation must retain the catalytic converter, oxygen sensor and any other emissions-control equipment required for the vehicle. Exhaust and emissions requirements vary between Australian states and territories, and the completed installation must comply with the regulations applicable in your state or territory.
