Advance Headers High-Performance Mild Steel Exhaust Extractors for Ford Falcon BA to BF 5.4L 4-Valve DOHC Boss V8 Engines
The Advance Headers Performance Exhaust Extractors (A64) are heavy-duty tubular manifolds purpose-built for the elite performance brackets of the Australian Barra/Boss-era Ford Falcon series. Custom-engineered specifically to clear the massive structural dimensions of the high-performance 5.4-Litre (330ci) 4-Valve Dual Overhead Cam (DOHC) Boss V8 engine housed within the BA and BF Falcon XR8, GT, GT-P, and FPV variants, this premium header upgrade completely replaces the highly restrictive factory cast iron log manifolds. By optimizing exhaust gas scavenging velocity and significantly dropping engine backpressure, it unlocks noticeable low-to-mid range torque, explosive top-end throttle response, and a deep, aggressive V8 growl worthy of Ford's iconic muscle platforms.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Left-Hand 5.4L 4V Boss Extractor Header Assembly
- 1 x Heavy-Duty Mild Steel Right-Hand 5.4L 4V Boss Extractor Header Assembly
Key Features:
- Engineered specifically to seamlessly integrate with the uniquely wide DOHC Boss V8 engine profiles inside BA-BF engine bays, clearing steering shafts, crossmembers, and starter motors
- Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing high-velocity exhaust gas flow and eliminating turbulence bottlenecks
- Substantially optimizes power bands across the entire RPM curve—ideal for improving street throttle crispness, overtaking power, and circuit performance profiles
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet thermal expansion cycles and typical high-torque performance V8 vibrations safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure exhaust leaks

⚠️ Crucial Engine Variant & Valve Architecture Alignment Warnings:
1. Strictly 4-Valve DOHC Boss V8 Models Only: This product (Part No. A64) is designed and space-mapped exclusively for the high-deck 5.4L 4-Valve Boss engine footprint. Because the exhaust port configurations, flange patterns, and physical engine widths differ substantially, these headers will NOT fit 3-Valve SOHC V8 engines (such as the Barra 220/230 found in standard Falcon V8 models).
2. Chassis Packaging Fit: Formed precisely to navigate past the factory rack and pinion steering systems and underbody transmission configurations unique to BA and BF performance sedans and utilities. Retains full integration with factory O2 feedback sensors.
Please Note: Due to the extremely tight physical clearances of the wide dual overhead cam V8 engine within the BA-BF engine bay and the estimated 4-hour technical fitment frame, professional installation by an exhaust specialist or qualified performance workshop is highly recommended.
