Wildcat WILD065 Daihatsu Rocky F80 & F85 2Y, 3Y & 4Y Exhaust Headers (1984–1990)

Wildcat WILD065 Exhaust Headers are engineered specifically for Daihatsu Rocky F80 and F85 four-wheel drive vehicles fitted with Toyota 2Y, 3Y and 4Y petrol engines. Manufactured in Australia by Wildcat Headers (Genie), these extractors provide a direct-fit replacement for the restrictive factory exhaust manifold while improving engine efficiency and overall drivability.

The proven interference header design promotes efficient exhaust scavenging by helping remove exhaust gases more effectively from each cylinder. This reduces pumping losses, improves cylinder filling and delivers stronger throttle response, increased low and mid-range torque and smoother engine performance, making these headers ideal for touring, off-road driving and everyday use.

Why Good Headers & Exhaust Systems Matter

At 4000rpm, Toyota 2Y, 3Y & 4Y engines move approximately 4,400L/min intake airflow and expel around 13,200L/min exhaust gas (@600°C).
At 5000rpm, airflow increases to approximately 5,500L/min intake and 16,500L/min exhaust output.

Efficient headers improve scavenging, reduce restriction and unlock usable horsepower and torque.
