Pacemaker PH4038 headers (extractors) are designed for Ford Falcon XR–XE models running 302 or 347 Windsor V8 engines fitted with aluminium cylinder heads using a 76mm dual bolt spacing. These competition-grade tri-Y headers maximise exhaust flow, improve mid-range torque, and deliver a crisp, aggressive exhaust note.

Why Good Headers & Exhaust Systems Matter

• At 5000rpm, a 302 Windsor moves approximately 10,500L/min intake airflow and expels around 31,500L/min exhaust gas
• At 6500rpm (600hp), airflow increases to approximately 22,000L/min intake and 66,000L/min exhaust output
• Efficient headers improve scavenging, reduce restriction and support usable horsepower and torque gains

Warranty & Compliance

• Backed by Pacemaker 2-year manufacturer warranty
