Mitsubishi Lancer CH 2.4L 4G69 MIVEC Headers – Wildcat WILD297

Wildcat WILD297 exhaust headers (extractors) are designed for the Mitsubishi Lancer CH fitted with the 2.4L 4G69 MIVEC petrol engine from 2005 to 2008.

Featuring an interference-style extractor design, WILD297 replaces the restrictive factory exhaust manifold and is designed to improve exhaust gas flow and scavenging.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.4L 4G69 engine draws in approximately 4,756 litres of intake air per minute and expels around 14,300 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 the header and exhaust connection before fully tightening all fasteners. 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 converter, oxygen sensors and any other emissions-control equipment required for the vehicle and comply with the regulations applicable in your state or territory.
