The 5.7-litre VZ-era cars get their own entry in the PH5363 family. This Pacemaker PH5363 (VZ 5.7L) is a Gen III competition header pair listed to fit the VZ Commodore and the WL Statesman / Caprice with the 5.7L V8.

What sets the VZ 5.7L listing apart?

Pacemaker splits the PH5363 range by car and engine, and this is the 5.7L build covering the VZ Commodore alongside the WL Statesman and Caprice. Matching the header to that specific Gen III 5.7L application and its mounting is why it carries this listing rather than the VY-series one. We confirm your model and engine against it before ordering.

What does a competition header change versus the cast manifold?

The factory cast manifold is a compact casting that prioritises packaging. A header replaces it with individual tuned-length tubular runners per cylinder before the merge — the change Pacemaker badges here as a competition header, the sharper end of the range. It bolts where the manifolds sat and feeds the system behind it.

Will it suit my VZ 5.7 or WL?

It's listed to the VZ Commodore and WL Statesman / Caprice in 5.7L form, supplied as an L/R pair for both banks. Pacemaker doesn't publish a primary tube diameter or material grade for this listing, so we won't state either — the workshop can confirm with the part in hand. Send your build and we'll match it.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men fits Pacemaker headers on-site. On the 5.7L Gen III we pull the cast manifolds, fit the L/R pair, and check clearance to the steering, crossmember and starter before joining it to the rest of the exhaust.

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

Common questions

Does the PH5363 (VZ 5.7L) cover the WL Caprice?
Yes — this listing fits the VZ Commodore and the WL Statesman and Caprice with the 5.7L V8, supplied as an L/R pair.
Is this the same as the VY Series II header?
No. This is the VZ 5.7L listing. The VY Series II uses a separate PH5363 part number — confirm your car with the workshop.
Does it suit the 6L LS2 VZ?
This is the 5.7L listing. The 6L VZ has its own PH5363 part number — let us know your engine and we'll match it.
