Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 4.8L TB48DE inline 6-cylinder engine theoretically draws in approximately 9,600 litres of intake air per minute and can expel around 28,800 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
• Allow the oxygen sensors to cool completely before removal
• Carefully remove the oxygen sensors and protect the sensor tips from contamination or impact
• Remove all traces of the old manifold gaskets and inspect the cylinder-head sealing surfaces
• Fit new DSF828 exhaust manifold/header gaskets where required
• Trial-fit the headers before fully tightening the mounting hardware
• Check clearance around the engine mounts, steering, transmission and surrounding components
• Protect the painted header surfaces during trial fitting and installation
• Check all exhaust and oxygen sensor connections after installation
• Inspect and re-tighten the mounting hardware after the initial heat cycles

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 converters, oxygen sensors and 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.
