The MPI Automotive FX-517 is a set of 4-into-1 tuned extractors listed to fit the Holden Commodore VE V8s, running 1-3/4in primaries into 3in 4-bolt flanged outlets.

What are extractors and what do they change?

Extractors, also called headers, take the place of the cast factory exhaust manifold that bolts to the cylinder head. The original casting bunches the ports together in a compact lump; extractors instead give each cylinder its own tuned primary tube before merging them. This set uses a 4-into-1 arrangement, so the four primaries on each bank gather into one collector, the 1-3/4in figure being the primary tube diameter. The aim is to let each cylinder's exhaust pulse clear with less interference; the trade-off against the cast manifold is the cost of the part and the labour to fit it.

What are the 3in 4-bolt flanged outlets for?

Each collector on the FX-517 finishes in a 3in outlet on a 4-bolt flange, as stated in the listing. The flange is the bolted joint where the extractors meet the rest of the exhaust, and a 4-bolt pattern at 3in sets how the next section connects on. That matters when planning the system behind the extractors, since the pipe that bolts up has to share that size and pattern. No power, weight or sound figures are published by the supplier.

Will it suit my Holden Commodore?

It is listed to fit the Holden Commodore VE across the V8 range, per the listing. The engine variant beyond "V8" is not given in the record, and extractors have to clear the steering, crossmember and chassis on a given car. Confirm the exact build with the workshop before ordering so the head flange pattern and the 3in outlets line up.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits extractors like these in-house across the Illawarra. Because the set bolts straight to the cylinder heads, we check the flanges seal cleanly on both banks, refit the oxygen sensors, and match the 3in outlets to the pipework behind them before signing it off. At an RRP of $885.73 it is a considered upgrade; send your VE build and we'll confirm the FX-517 is the right set.

Common questions

Will the FX-517 fit my Commodore?
It is listed to fit the Holden Commodore VE V8s. The exact engine variant isn't specified in the listing, so confirm your build with the workshop before ordering.
What size are the outlets?
The FX-517 finishes in 3in outlets on a 4-bolt flange, so the pipework that bolts up behind it needs to match that size and bolt pattern.
What does 4-into-1 tuned mean on this set?
Each bank's four 1-3/4in primary tubes merge into a single collector rather than being cast together, which is the 4-into-1 layout described in the listing.
