Category: Extractors and headers


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.
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.
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.
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.
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.
