Fitment Notes

Confirm that the vehicle is fitted with the 1.5L G4FK DOHC 16-valve engine before ordering. This is particularly important with X3 Excel models because earlier vehicles were also produced with the 1.5L SOHC engine.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal to assist disassembly and installation.

What's Included

Wildcat WILD055 header assembly. Exhaust manifold/header gaskets are not included unless specifically supplied or shown with the product.

Recommended With

RBG055 exhaust manifold/header gasket is the gasket application specified for WILD055.

Why Good Headers & Exhaust Systems Matter

The 1.5L engine theoretically draws approximately 3,000 litres of intake air per minute at 4,000 rpm at 100% volumetric efficiency. Once combustion has taken place, the hot exhaust gases occupy substantially more volume as they travel through the exhaust system.

Using an illustrative exhaust temperature of approximately 600°C, this represents around 9,000 litres of exhaust gas per minute. 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

Professional installation is recommended. Check the exhaust system alignment, mounting points and surrounding clearances during installation.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal. After installation and several heat cycles, inspect the system for exhaust leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

Installation and use must comply with applicable Australian state or territory regulations, including requirements relating to emissions equipment, catalytic converters, exhaust noise and vehicle modifications.
