Description
Advance Headers High-Performance Heavy-Duty Mild Steel Exhaust Extractors for Toyota Land Cruiser 40 & 55 Series 4.2L 2F Inline 6-Cylinder Petrol Engines (1975–August 1980)
The Advance Headers Performance Exhaust Extractors (A200HB) are heavy-duty mild steel tubular manifolds custom-engineered explicitly for the classic early-generation iterations of the legendary Toyota Land Cruiser 4WD family. Tailored precisely to fit the highly robust, torque-rich 4.2-Litre (2F) Overhead Valve (OHV) inline 6-cylinder petrol engine housed within the short-wheelbase FJ40, long-wheelbase FJ45 utility, and rare FJ55 station wagon platforms, this rugged upgrade replaces the highly restrictive factory cast iron log manifold structure. By dropping heavy engine backpressure and optimizing exhaust gas scavenging velocity, it unlocks vital low-to-mid range torque, sharpens off-road throttle response, and delivers a clean, deep, and commanding classic inline-6 engine note.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel 6-Cylinder Performance 2F Petrol Extractor Assembly
Key Features:
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet thermal cycles, extreme trail vibration, and demanding commercial workloads safely
- Mandrel-bent primary tubes completely remove the extreme gas restrictions native to the factory cast iron logs, smoothing flow geometry to maximize working efficiency
- Precision-mapped packaging architecture engineered to safely clear old-school mechanical steering gear systems, under-bonnet brake hardware, and front firewalls
- Substantially optimizes low-to-mid range working torque delivery—ideal for restoring low-range crawling control, off-road tractability, and everyday cruising acceleration
- 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 gas leaks

⚠️ Crucial Accessory Interface & Year Range Alignment Warnings:
1. Strict Power Take-Off (P.T.O.) Winch Exclusion: This product (Part No. A200HB) is custom-routed to maximize clearance in standard engine bays. Due to primary tube routing tolerances, it will NOT fit vehicles equipped with a mechanical P.T.O. Winch system because the extractor assembly physically collides with the mechanical drive shaft path running from the transfer case forward.
2. Strict Production Date Window (1975 - August 1980): Flange-mapped explicitly for early 2F configurations. Models built from September 1980 onward featured revised intake/exhaust heat riser combinations and alternate emissions configurations that will not align with this kit without custom modification.
3. Excludes Diesel Applications: Designed purely for petrol variants; will not bolt onto B, 2B, 3B, or H series diesel cylinder heads.
Please Note: Professional installation by a vintage 4WD exhaust specialist or qualified mechanical workshop is highly recommended to guarantee proper system alignment, optimal firewall clearance, and a perfect leak-free seal on classic cylinder heads.
