Category: Extractors and headers


The MPI Automotive FX-509HPC-B is a ceramic-coated (black) set of four-into-one extractors listed to fit the Holden Commodore VT, VX, VU, VY and VZ with the 5.7L and 6.0L V8. It runs a 1-7/8in primary, so it's a front-of-system header upgrade rather than a tailpipe change.
The FX-509HPC-B 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 layout on a 1-7/8in primary. They cover the run 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 V8 like the 5.7L and 6.0L the aim is freer breathing out of the heads. The black ceramic coating is a heat-management and finish choice, not a performance claim. The honest trade-offs: tubular headers change the exhaust note, they sit in a tight engine bay so clearance matters, and sensors and heat shields usually need transferring. We publish no power or sound figures for the FX-509HPC-B.
The FX-509HPC-B is listed to fit the VT, VX, VU, VY and 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 silver-coated version and an uncoated version, so confirm finish, engine and exact body code with the workshop before ordering.
Oak Flats Muffler Men supplies and fits extractors like the FX-509HPC-B in-house across the Illawarra. It is head-end labour in a tight V8 bay: freeing the original manifolds, transferring sensors and shields, and checking clearance and gasket seal at both heads before the rest of the system goes back on. It carries a recommended retail price of $2282.45, supplied by MPI Automotive; if it is not on the shelf we order it in.
