The MPI Automotive FX-509 is a 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, and is listed to pair with the Manta SSMBC718/720 system.

What does this set of extractors cover?

The FX-509 is the extractor stage for the V8 Commodore — tubular headers that bolt 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, sized to match the Manta SSMBC718/720 system noted in the listing. They cover 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, rather than the short shared passages of a cast manifold. On a large-capacity V8 the aim is freer breathing out of the heads, which is why this set is matched to a 3in catback. 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-509.

Will it suit my Holden Commodore?

The FX-509 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. This is the uncoated version of the casting — ceramic-coated silver and black versions exist separately — and it is listed to suit the Manta SSMBC718/720, so confirm engine, body code and the matching catback with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits extractors like the FX-509 in-house across the Illawarra. It is head-end labour on a tight V8 bay: freeing the original manifolds, transferring sensors and shields, and checking clearance and gasket seal at both heads. It carries a recommended retail price of $1494.15, 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.

Will it fit my VT–VZ Commodore?

Is this the coated or uncoated version?
The FX-509 is the uncoated set. Ceramic-coated silver and black versions are listed separately as the FX-509HPC-S and FX-509HPC-B.
