Advance Headers High-Performance Mild Steel Inside Chassis Exhaust Extractors for TOYOTA Landcruiser 2H 4.0L Diesel Engines
The Advance Headers Performance Inside Chassis Exhaust Extractors (A232) are precision-engineered for Toyota's legendary 4.0-Litre 2H inline 6-cylinder naturally aspirated diesel workhorse engine. Spanning classic Landcruiser generations including the HJ45, HJ47, HJ60, and HJ75, this heavy-duty tubular header upgrade utilizes a specialized inside-the-chassis rail configuration. It is engineered to maximize exhaust gas scavenging velocity, decrease restrictive backpressure, lower exhaust gas temperatures (EGTs), and unlock vital low-end grunt.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Inside Chassis Performance Exhaust Extractor Header Assembly (Standard Finish)
Key Features:
- Tuned inside chassis-rail configuration routes primary lines cleanly within the vehicle's frame structure, providing superior protection against harsh off-road terrain and rocks
- Mandrel-bent high-flow primary pipelines maintain completely uniform internal geometry, sweeping out heavy diesel exhaust gas efficiently to reduce thermal engine stress
- Substantially optimizes low-end torque delivery and mid-range pulling power—critical for heavy towing, remote outback touring, and recovery work
- Heavy-duty mild steel construction structurally built to handle severe diesel vibration cycles, thermal loads, and rugged commercial use safely
- Thick, precision laser-cut cylinder head flanges maintain a perfectly flat, stable mating footprint to permanently guard against warping and gas leaks

Winch setup. Please check your recovery gear configuration before placing an order.
