Pacemaker PP5363-31 is a tuned-length header set built for the wagon body — VT, VX and VY Series 1 V8 Holdens in long-roof form — paired with a 2in system to suit the load-area floorpan that a sedan doesn't share. The 1⁻₇⁄₈in primaries are tuned-length, so the runner lengths are matched rather than arbitrary.

Why a wagon-specific header set?

The wagon floorpan, rear suspension mounting and load-area sheet metal sit differently to a sedan or ute, and that changes where pipework can run underneath. This PP5363-31 listing is cut for the VT–VY Series 1 V8 wagon specifically, so the tuned-length runners and the 2in system are routed for that body rather than forced to fit it. Pacemaker lists it against the Holden wagon; we treat that as listed-to-fit and confirm against your actual car.

What does a tuned header do versus the cast manifold?

A factory cast manifold dumps each cylinder's exhaust into a shared lump close to the head; a tuned-length header gives every cylinder its own mandrel-bent runner of matched length before they merge, which lets the gas pulses leave more cleanly. On a VT–VY V8 that's the first restriction most owners address. This is the headers-plus-system package at a 2in bore, not a tailpipe trim, so it changes the engine-back run.

Is it road legal?

These are tuned extractors, not a catalytic converter or muffler, so there's no emissions device built into the part itself. Whether your VT–VY wagon stays compliant depends on what's downstream and how the whole system is signed off to NSW requirements, which we go through per car. Pacemaker publishes no compliance approval for the set and we won't imply one.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Pacemaker header sets like this in-house across the Illawarra. We match the PP5363-31 listing to your VT, VX or VY Series 1 wagon, check the runners clear the steering and crossmember, and seal each port with fresh gaskets. Listed RRP is 4240.03 AUD; the fitting charge is quoted once the wagon is on the hoist.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

Will the PP5363-31 fit my VT–VY Series 1 wagon?
It's listed to fit the VT, VX and VY Series 1 V8 Holden wagon. Send us your exact build and we'll confirm the fitment before ordering.
Is this the full system or just the headers?
This package is the tuned headers with the 2in system. It's an engine-back change, not a tailpipe-only swap.
