Advance Headers High-Performance Mild Steel Exhaust Extractors for Mitsubishi Magna TM to TS 4-Cylinder Engines
The Advance Headers Performance Exhaust Extractors (A346i) are engineered specifically for the classic Australian-built Mitsubishi Magna 4-cylinder sedan and wagon families. Covering a massive production run from the TM, TN, and TP series through to the updated TR and TS generations, this heavy-duty tubular header upgrade replaces the restrictive factory cast iron log manifold. Custom-profiled to maintain total versatility across all early fuel variants, this kit delivers a universal fit for early leaded carburetted motors as well as later-generation unleaded Electronic Fuel Injection (EFI) engine layouts, drastically improving low-to-mid range torque and throttle response.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Assembly
Key Features:
- Dual-fuel layout mapping provides full physical compatibility with both classic leaded carburetted setups and updated unleaded multi-point EFI delivery networks
- Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity and eliminating heavy factory casting restrictions
- Substantially optimizes low-to-mid range torque delivery—ideal for restoring throttle response, maintaining highway cruising efficiency, and navigating daily street driving smoothly
- Heavy-duty mild steel construction structurally built to handle intense under-bonnet thermal transitions and demanding front-wheel-drive operational heat cycles safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping, face distortion, and high-pressure exhaust leaks

⚠️ Crucial Model Generation & Architecture Notes:
1. 4-Cylinder Models Only: This product (Part No. A346i) is designed exclusively around the 2.6L Astron 4-cylinder engine platform. It will strictly NOT line up or fit onto contemporary Magna V6 luxury variants (e.g., 3.0L 6G72 lines found in TR-TS series), which require a completely separate multi-bank manifold assembly.
2. Downstream Alignment: Tailored to fit transverse engine configurations within standard factory floor parameters. Custom or modified downstream aftermarket exhaust pipes may require alignment tracking during workshop hookup.
Please Note: Professional installation by an exhaust specialist or qualified classic automotive mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
