Mazda 6 GG 2.3L L3-VE Headers – Wildcat WILD296

Wildcat WILD296 exhaust headers (extractors) are designed for the Mazda 6 GG fitted with the 2.3L L3-VE DOHC petrol engine from 2002 to 2005.

Featuring a tuned-length design, WILD296 replaces the restrictive factory exhaust manifold and is designed to improve exhaust gas flow and scavenging. Mandrel-bent pipework provides smoother exhaust flow to help improve torque, throttle response and overall engine performance, making these headers well suited to everyday street and performance applications.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.3L L3-VE engine draws in approximately 4,522 litres of intake air per minute and expels around 13,566 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.
