Nissan Navara D22 3.3L V6 VG33E Headers – Wildcat WILD702

Wildcat WILD702 exhaust headers (extractors) are designed for the Nissan Navara D22 fitted with the 3.3L V6 VG33E petrol engine from 2003 to 12/2005.

Featuring an interference-style extractor design, WILD702 replaces the restrictive factory exhaust manifolds and is designed to improve exhaust gas flow and scavenging. The larger mandrel-bent pipework helps improve low and mid-range torque, throttle response and overall engine performance, making these headers well suited to street, touring and 4WD applications.

What’s Included

• Wildcat WILD702 header / extractor assemblies

• Free-flowing exhaust system for further reduction in exhaust restriction

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 3.3L VG33E V6 draws in approximately 6,550 litres of intake air per minute and expels around 19,650 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. Trial-fit both headers and exhaust connections before welding or fully tightening the system. Protect the painted surfaces during installation to minimise scratching or damage.

Warranty & Compliance

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

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