Holden VZ 6.0L 8 Cylinder 1 7/8 Tuned Headers 3" Inch System With Rear Pipe Only.
Category: Extractors and headers


The 1-7/8in primary tubing is what defines the Pacemaker PP5363-54: a large-bore tuned header set feeding a 3in system, listed to fit the Holden VZ 6.0L eight-cylinder. It's the rear-pipe-only build, supplied without the muffler section.
Primary bore is an application choice, and the PP5363-54 sits at the larger end with 1-7/8in runners. Bigger primaries like this favour higher-rpm, higher-output eight-cylinder builds, giving the gas room to move once the engine is working hard, rather than chasing the very low-down response that smaller tubing keeps. On the 6.0L VZ that bore is matched to a 3in system behind it, so the header isn't choked by a tighter pipe downstream.
Tuned headers, also called extractors, replace the factory cast manifolds with separate tubular runners off each cylinder, with the primary lengths matched so the cylinders scavenge in step. The PP5363-54 changes the exhaust side of the engine; it's part of the wider exhaust rather than an internal component, and it works with whatever sits downstream.
It's listed to fit the Holden VZ with the 6.0L eight-cylinder. Because header fitment is sensitive to the precise variant, confirm your exact VZ model and that it's the 6.0L with the workshop before ordering this rear-pipe-only set.
Oak Flats Muffler Men fits tuned headers like the PP5363-54 in-house across the Illawarra. The job needs good access to drop the factory manifolds, fresh gaskets, and the 3in rear pipework behind the extractors, with the muffler arrangement discussed since this build comes without one. Supplied by Pacemaker at $4,257.79 AUD; send your VZ details and we'll confirm the fit.
