Advance Headers High-Performance Mild Steel Exhaust Extractors for Mitsubishi Astron 2.0L & 2.6L 8-Valve Engines
The Advance Headers Performance Exhaust Extractors (A342) are precision-engineered for the legendary Mitsubishi Astron engine family (including 2.0-Litre 4G52 and 2.6-Litre 4G54 configurations). Serving a huge range of classic Australian-market rear-wheel drive and four-wheel drive passenger cars, commercial utilities, and classic SUVs, this heavy-duty tubular header upgrade replaces your highly restrictive factory cast iron log manifold to maximize exhaust scavenging velocity, lower engine backpressure, and unlock true low-to-mid range working torque.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Assembly (Standard Finish)
Key Features:
- Tuned mandrel-bent primary piping pathways ensure completely uniform gas flow routing, eliminating the restrictive flow bottlenecks found in original cast manifolds
- Substantially optimizes overall exhaust velocity, delivering sharper throttle response and noticeable low-to-mid range torque gains—perfect for daily driving, heavy load carrying, towing, and off-roading
- Heavy-duty mild steel construction structurally built to handle severe thermal expansions and demanding operational heat cycles safely
- Thick, precision laser-cut cylinder head flanges maintain flush mating boundaries to guard permanently against warping and exhaust gas leaks
- Engineered as a multi-fit direct bolt-on solution designed to clear standard steering tracks, mechanical linkages, and front 4WD driveshaft sections cleanly
Specifications:
- Brand: Advance Headers
- Part Number: A342
- Material: Mild Steel (Standard Finish)
- Engine Suitability: Mitsubishi Astron 2.0L & 2.6L SOHC 8-Valve Petrol (4G52 / 4G54 Carburettor Only)
- Component Type: Performance Exhaust Extractors / Headers
- Estimated Fitting Time: 1.5 Hours
- Welding Required: No (Direct Bolt-On to Cylinder Head)
⚠️ Crucial Engine & Cylinder Head Compatibility Warning:
This product (Part No. A342) is configured explicitly for original 8-valve single overhead cam (SOHC) Carburettor variations of the Mitsubishi Astron engine block. It will not align properly with later multi-valve configurations or 16-valve Magnum variants due to differences in port placement and mounting patterns. Please verify your vehicle's engine identification codes and build plate metrics prior to finalizing your order.
Please Note: Professional installation by an exhaust specialist or qualified classic automotive mechanic is highly recommended to guarantee proper system mapping and a perfect leak-free seal.
