The MPI Automotive FX-509HPC-S is a ceramic-coated (silver) set of extractors listed to fit the Holden Commodore VT–VZ with the 5.7L and 6.0L V8. It runs a 1-7/8in primary into a 3in outlet in a four-into-one layout, so it's a front-of-system header upgrade rather than a tailpipe change.

What does this set of extractors cover?

The FX-509HPC-S is the extractor stage for the V8 Commodore — tubular headers bolting to the heads in place of the cast manifolds. The slug describes a four-into-one design with a 1-7/8in primary feeding a 3in outlet. They cover the run from the head flanges to the collector; the cat, pipework and mufflers behind them are separate parts.

What are extractors and what do they change?

Extractors give each cylinder its own primary pipe before merging at the collector, instead of the short shared passages of a cast manifold. On a large-capacity V8 like the LS-family 5.7L and 6.0L the aim is freer breathing out of the heads. The silver ceramic coating is a heat-management and finish choice rather than a performance claim. The honest trade-offs: tubular headers change the exhaust note, they sit in a tight bay so clearance matters, and sensors and shields usually need carrying across. We publish no power or sound figures for the FX-509HPC-S.

Will it suit my Holden Commodore?

The FX-509HPC-S is listed to fit the VT–VZ Commodore with the 5.7L or 6.0L V8; treat that as a starting point, not a guarantee, because catalogue feed data can be imperfect. The same casting is offered in a black-coated version and an uncoated version, so confirm finish, engine and exact body code with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits extractors like the FX-509HPC-S in-house across the Illawarra. It is head-end labour on a tight V8 bay: freeing the original manifolds, transferring oxygen sensors and shields, and checking clearance and gasket seal at both heads before the system goes back on. It carries a recommended retail price of $1875.02, supplied by MPI Automotive; if it is not on the shelf we order it in.

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

Common questions

What's the difference between the silver and black FX-509HPC?
Both are the same ceramic-coated four-into-one extractor; the FX-509HPC-S is finished silver and the FX-509HPC-B black. Confirm which finish you want with the workshop before ordering.
Will it fit my VT–VZ Commodore?
It's listed to fit the VT–VZ Commodore with the 5.7L or 6.0L V8. Catalogue data can vary by build, so confirm your exact variant with the workshop first.
Does it include a catalytic converter?
No — the FX-509HPC-S is the extractor stage only. The cat, pipework and mufflers behind it are separate parts.
