Advance Headers | Mild Steel Exhaust Extractors | Ford Mustang 64-73 Fairlane 289-302 Windsor | A55

PRODUCT CONTENTS:

• 1 x Heavy-Duty Mild Steel Left-Hand Windsor V8 Extractor Header Assembly
• 1 x Heavy-Duty Mild Steel Right-Hand Windsor V8 Extractor Header Assembly

Key Features:

• Engineered specifically to seamlessly clear factory power steering boxes and hydraulic lines without binding or physical contact
• Universally accommodates automatic gearboxes as well as modern or converted hydraulic manual clutch systems
• Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and removing heavy factory casting restrictions
• Heavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and high-vibration muscle car applications safely
• Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping and high-pressure exhaust leaks

⚠️ Crucial Component & Drivetrain Compatibility Exclusions:
1. Mechanical Clutch Linkage Exclusion: This product (Part No. A55) will NOT fit models equipped with a factory mechanical Z-bar or mechanical clutch linkage system. The primary pipe pathways will physically conflict with the linkage mechanisms. It is fully compatible with automatic transmissions or hydraulic conversion clutches only.
2. Cylinder Head Exhaust Port Restriction: Configured strictly to match traditional standard factory Windsor V8 cylinder head exhaust port coordinates. These headers will NOT fit GT40 or GT40P cylinder heads (often sourced from late-model Explorer/Falcon V8 engines) due to altered spark plug angles and matching flange constraints.

Please Note: Due to tight engine bay parameters across early Ford muscle car shock towers, professional installation by a classic vehicle exhaust specialist or qualified restoration workshop is highly recommended.
