Ford Falcon XR XT XW XY 289 302 Windsor GT40P Pacemaker Headers PH4032

Pacemaker PH4032 headers (extractors) are designed for Ford Falcon XR, XT, XW and XY models fitted with 289, 302 or 5.0L EFI Windsor V8 engines. PH4032 is compatible with both standard Windsor cylinder heads and GT40P cylinder heads, providing a performance header option for classic Falcon Windsor V8 applications and later 5.0L Windsor engine combinations.

PH4032 features Pacemaker's TUNED design with 41mm (1⅝") primary pipes and 76mm (3") outlets. The larger primary and outlet configuration is designed to improve exhaust flow, torque, throttle response and engine performance.

GT40P COMPATIBLE – PH4032 is designed to accommodate the different spark-plug angle found on GT40P cylinder heads as fitted to the AU II 302 Windsor.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, a 289ci (4.7L) Windsor V8 theoretically draws approximately 9,400 litres of intake air per minute at 100% volumetric efficiency and expels around 28,200 litres of hot exhaust gas per minute at approximately 600°C.

At the same engine speed, a 302ci / 5.0L Windsor V8 theoretically draws approximately 10,000 litres of intake air per minute and expels around 30,000 litres of hot exhaust gas per minute at approximately 600°C.

Actual airflow varies with RPM, engine load, volumetric efficiency, camshaft specification and engine condition. These figures are theoretical values intended to illustrate the substantial volume of gas that must pass through the exhaust system at higher engine speeds.

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

• Confirm the engine and cylinder-head combination before installation, particularly where GT40P cylinder heads have been fitted.
• Apply penetrating lubricant to existing exhaust fasteners before removal.
• Remove all traces of the old manifold gaskets and inspect the cylinder-head sealing surfaces.
• Fit new DSF3 exhaust manifold/header gaskets.
• Trial-fit both header assemblies and check all clearances before fully tightening the mounting hardware.
• Check spark-plug and plug-lead clearance carefully on GT40P-head applications.
• Check clearance around the steering, starter motor, engine mounts, transmission and surrounding components.
• Protect painted or ceramic-coated surfaces during trial fitting and installation.
• Check all exhaust connections for leaks after installation.
• Inspect header mounting hardware after the initial heat cycles.

Warranty & Compliance

Pacemaker PH4032 headers are covered against manufacturing defects subject to Pacemaker's current warranty terms and conditions.

Any modified engine, cylinder-head or exhaust installation must comply with applicable state or territory requirements covering vehicle modifications, exhaust noise and roadworthiness.
