Category: Extractors and headers


The MPI Automotive FX-508HPC-B is a ceramic-coated (black), long-tube 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 1-3/4in primary, so it's a front-of-system header upgrade rather than a tailpipe change.
The FX-508HPC-B is the long-tube 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 1-3/4in primary. They cover the run from the head flanges to the collector; the cat, pipework and mufflers behind them are separate parts.
Long-tube extractors give each cylinder an extended primary pipe before merging at the collector, sitting further back than a shorty header. On a large V8 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 are sharper with long tubes: they reach further down the chassis so clearance is tighter, the exhaust note changes, and sensors and shielding usually need transferring or relocating. We publish no power or sound figures for the FX-508HPC-B.
The FX-508HPC-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 long-tube casting is offered silver-coated as the FX-508HPC-S, so confirm finish, engine and exact body code with the workshop before ordering.
Oak Flats Muffler Men supplies and fits long-tube extractors like the FX-508HPC-B in-house across the Illawarra. Long tubes are a bigger job than shorties: freeing the original manifolds, routing the longer primaries clear of steering and crossmember, transferring sensors and shields, and checking clearance and gasket seal at both heads. It carries a recommended retail price of $2146.01, supplied by MPI Automotive; if it is not on the shelf we order it in.
