The Pacemaker KB9505-HXMX is a long-wheelbase header kit for the GQ Nissan Patrol, listed for the 4.2L petrol (non-EFI) and diesel wagon from 1987 to 1997. What sets it apart is the GQ Patrol application itself — a long, heavy 4x4 wagon where the kit's 2in primaries replace the cast manifold and feed a single 2½in run sized for low-down torque off-road, not top-end power.

What's specific to the GQ Patrol fitment?

This KB9505-HXMX is built around the long-wheelbase GQ Patrol wagon. The 2in primary headers are sized to keep gas speed up on a torquey 4.2L, which suits the low-rev work a heavy 4x4 actually does. As a header kit it includes the pipework and hardware to complete the front of the system, bolting to the factory location on the GQ.

Non-EFI petrol and diesel — what's listed?

The kit is listed for the 4.2L in non-EFI petrol and diesel form across 1987 to 1997. The non-EFI qualifier is part of the record — confirm your fuel and induction setup with the workshop, since the engine variant affects how the headers meet the head and the rest of the run.

Is it road legal?

This is a header kit rather than a cat-delete on a road-relevant exhaust system, so the part carries no off-road-only restriction of its own. Header and exhaust compliance still varies by state, so confirm your registration requirements with the workshop before fitting.

What does fitting involve at the Illawarra workshop?

Oak Flats Muffler Men supplies and fits these Pacemaker Patrol kits on-site. On a long-wheelbase GQ the single 2½in run and 2in primaries are checked for clearance against the chassis and steering before the bay is booked. Send your build — non-EFI petrol or diesel — and we'll confirm the listed fitment.
