Category: Extractors and headers


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.
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.
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.
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.

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.
