Holden Commodore VN VP VR VG 3.8L V6 Getrag Manual Headers – Wildcat WILD032MG

Wildcat WILD032MG exhaust headers (extractors) are designed for selected Holden Commodore VN, VP, VR and VG models fitted with the 3.8L V6 petrol engine and Getrag manual transmission with hydraulic-operated clutch.

Featuring an interference-style design, WILD032MG replaces the restrictive factory exhaust manifolds with larger performance pipework designed to improve exhaust gas flow and scavenging. Reduced exhaust restriction can improve torque, throttle response and overall engine performance.

WILD032MG is a direct-fit application and is designed to suit vehicles equipped with variable power steering. It is also listed for applicable Calais and Statesman models using the same 3.8L V6 and compatible Getrag manual transmission configuration.

Important: WILD032MG suits Getrag manual transmission applications with a hydraulic-operated clutch.

Please check availability before ordering.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the Holden 3.8L V6 draws in approximately 7,600 litres of intake air per minute and expels around 22,800 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 check engine, transmission, hydraulic clutch components, steering and body clearance before final tightening. Inspect the existing exhaust connections and mounting hardware and replace damaged or corroded components where required.

Warranty & Compliance

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

Installation must retain the catalytic converters, oxygen sensors 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.
