Vehicle Fitment

• Make: Mazda
• Model: B2600
• Year Range: 1988-1994
• Engine: Mazda G6
• Capacity: 2.6L
• Configuration: SOHC 12-valve inline four-cylinder petrol

IMPORTANT: Suits the Mazda G6 SOHC 12-valve engine ONLY.

The 1988-1994 range is the Advance application range for A477. Because different engine configurations can be found within the B2600 range, engine identification should be confirmed before ordering rather than relying on the vehicle year alone.

Fitment Notes

G6 Engine Only: Advance A477 is specifically designed for the Mazda 2.6L G6 SOHC 12-valve petrol engine.

Do not order A477 solely because the vehicle is a 1988-1994 B2600. Confirm that the vehicle is fitted with the Mazda G6 SOHC 12-valve engine.

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

What's Included

• 1 x Advance A477 header assembly
• Header/manifold gaskets

Bolts and other installation hardware should not be assumed to be included unless confirmed with the current product before ordering.

Recommended With

Before installation, inspect the existing exhaust system, engine mounts, gaskets, mounting studs and associated hardware.

Contact Best Mufflers if you require advice on replacement exhaust components to complete the installation.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.6L G6 four-cylinder engine theoretically draws approximately 5,200 litres of intake air per minute at 100% volumetric efficiency.

Using an illustrative hot exhaust volume at approximately 600°C, this represents around 15,600 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 removing the original exhaust manifold, confirm that the vehicle is fitted with the Mazda G6 SOHC 12-valve engine.

Professional installation is recommended. Inspect the condition of the engine mounts, exhaust system, mounting studs and associated hardware before fitting the headers.

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 exhaust system and flex section for leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

The vehicle's required catalytic converter and other 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.
