Mitsubishi Triton MK 1996-2006 3.0L 6G72 V6 24V Advance Exhaust Headers A348

Advance A348 headers (extractors) are designed for the Mitsubishi Triton MK from 1996 to July 2006 fitted with the 3.0L 6G72 SOHC 24-valve V6 petrol engine.

Suitable for applicable 2WD and 4WD Triton MK models, these Australian-made mild-steel 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.

EGR: Models requiring an EGR fitting use Advance A348E.

AUTOMATIC TRANSMISSION: Automatic models require modification/repositioning of the Y-pipe at the catalytic converter flange.

Bolts and gaskets are included.

Please check availability and current lead time before ordering.

Construction

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

They are designed as a performance replacement for the original exhaust manifolds on Mitsubishi Triton MK models fitted with the correct 3.0L 6G72 SOHC 24-valve V6.

Additional Options

Advance A348E is available for Triton models requiring an EGR fitting. Check the existing 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 Triton.

Vehicle Fitment

• Make: Mitsubishi
• Model: Triton
• Series: MK
• Year Range: 1996-July 2006
• Engine: 6G72
• Capacity: 3.0L / 2972cc
• Configuration: SOHC 24-valve V6 petrol
• Drive: 2WD and 4WD
• Transmission: Manual and automatic – see automatic fitment note below

ENGINE IDENTIFICATION: A348 is specifically designed for the 24-valve version of the 3.0L 6G72 V6. Do not order for an earlier 12-valve 6G72 engine.

Fitment Notes

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

2WD & 4WD: A348 is listed for applicable 2WD and 4WD Mitsubishi Triton MK models.

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

Automatic Transmission: Automatic models require modification/repositioning of the Y-pipe at the catalytic converter flange. For this reason, A348 should not be described as a completely bolt-on installation across every Triton application.

Because these vehicles are now older, exhaust and emissions systems may have been replaced or modified. Check the engine, EGR configuration and existing exhaust system before ordering.

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 Triton models requiring an EGR connection, 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 Triton 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 Y-pipe at the catalytic converter flange.

Professional installation by an exhaust specialist is recommended, particularly for automatic transmission models requiring outlet modifications.

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, inspect the complete exhaust system for leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

Advance A348 mild-steel headers are covered by a 1-year structural warranty.

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.
