Mitsubishi Challenger PA 1998-2006 3.0L 6G72 V6 24V Advance Exhaust Headers A348

Advance A348 headers (extractors) are designed for the Mitsubishi Challenger PA 4WD 1998-2006 fitted with the 3.0L 6G72 SOHC 24-valve V6 petrol engine.

These Australian-made headers provide a performance replacement for the original exhaust manifolds, helping improve exhaust flow, torque, throttle response and engine performance.

IMPORTANT: A348 suits the 6G72 24-valve engine ONLY. It does not suit earlier 12-valve 6G72 applications.

Automatic transmission models require modification/repositioning of the outlet/Y-pipe at the catalytic converter flange.

AUTOMATIC TRANSMISSION: The outlet/Y-pipe flange requires modification or repositioning at the catalytic converter on automatic models.

Bolts and gaskets are included.

Please check availability and current lead time before ordering.

Construction

Advance A348 headers are Australian Made and feature heavy-duty, press-bent construction.

They are designed as a performance replacement for the original exhaust manifolds on the Mitsubishi Challenger PA fitted with the correct 3.0L 6G72 SOHC 24-valve engine.

Additional Options

Advance A348E is available for vehicles requiring an EGR fitting. Check your vehicle before ordering to determine whether A348 or A348E is required.

Please contact Best Mufflers if you are unsure which version is correct for your Challenger.

Vehicle Fitment

• Make: Mitsubishi
• Model: Challenger
• Series: PA
• Year Range: 1998-2006
• Engine: 6G72
• Capacity: 3.0L / 2972cc
• Configuration: SOHC 24-valve V6 petrol
• Drive: 4WD
• Transmission: Manual and automatic – see automatic fitment note below

ENGINE IDENTIFICATION: A348 is specifically for the SOHC 24-valve version of the 3.0L 6G72 V6. Do not order for a 12-valve 6G72 application.

Fitment Notes

24-Valve Engine Only: Advance A348 is designed for the 3.0L 6G72 SOHC 24-valve V6 fitted to the PA-series Challenger.

EGR: If the vehicle requires an EGR fitting, use Advance A348E rather than A348.

Automatic Transmission: The outlet/Y-pipe at the catalytic converter flange requires modification or repositioning on automatic transmission models.

Catalytic Converter: The supplied Advance application information specifies that the catalytic converter must be located on the right-hand side. Check the existing exhaust configuration before ordering.

Because these vehicles are now older, exhaust systems and emissions equipment may have been replaced or modified. Check the existing vehicle configuration before installation.

What's Included

• 1 x Advance A348 header/extractor assembly
• Gaskets
• Bolts

Recommended With

Before installation, inspect the existing catalytic converter, Y-pipe, exhaust system, oxygen sensors, engine mounts and associated mounting hardware.

For vehicles requiring EGR provision, use Advance A348E.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 3.0L 6G72 V6 theoretically draws approximately 6,000 litres of intake air per minute at 100% volumetric efficiency.

Using an illustrative hot exhaust volume at approximately 600°C, this represents around 18,000 litres of exhaust gas per minute.

A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

Before installation, confirm that the vehicle is fitted with the 3.0L 6G72 SOHC 24-valve V6 and determine whether an EGR fitting is required.

On automatic transmission models, allow for modification or repositioning of the outlet/Y-pipe at the catalytic converter flange.

Professional installation by an exhaust specialist is recommended because of the catalytic converter and outlet alignment requirements.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal to assist with easier removal and installation.

After installation and several heat cycles, check the complete exhaust system for leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

The vehicle's catalytic converter, oxygen sensors, EGR system where fitted, and other required emissions-control equipment must remain correctly installed and operational.

Installation must comply with applicable Australian state or territory requirements relating to emissions, exhaust noise and vehicle modifications.

FAQ

What vehicle does Advance A348 fit?
A348 is designed for the Mitsubishi Challenger PA 4WD 1998-2006 fitted with the 3.0L 6G72 SOHC 24-valve V6 petrol engine.
