Category: Extractors and headers


The MPI Automotive FX-515 is an extractor set listed to fit the Holden Commodore VF V8s. It's a 4-into-1 tuned-length design on 1 3/4in primaries, finishing in 3in 4-bolt flanged outlets, replacing the factory cast manifolds with tube-style headers.
This is a header replacement for the front of the exhaust on the V8 VF Commodore. As a V8, it covers both cylinder banks, swapping the cast factory manifolds for tubular runners. The listing describes a 4-into-1 tuned design on 1 3/4in primary tubes, finishing in 3in outlets with a 4-bolt flange per side. Those flanged outlets give a defined, repeatable join to the next section, making it straightforward to connect up the rest of the system.
An extractor merges each cylinder's exhaust through tubes of more even length than a cast manifold, aiming to ease back-pressure out of the heads at the front-most, hottest point of the system. A 4-into-1 tuned-length layout collects all four primaries from a bank into one collector, with primary length chosen as part of the design — a common header geometry on a V8. The 1 3/4in primary figure in the listing describes the diameter of those individual runner tubes.
The FX-515 is listed to fit the V8 VF Commodore with this 4-into-1, 1 3/4in primary design and 3in 4-bolt flanged outlets. Confirm your exact V8 model with the workshop before ordering, and note there's a separate VE-specific set if yours is the earlier model.
Oak Flats Muffler Men fits Commodore extractors in-house across the Illawarra. A V8 header swap means working both banks, fitting fresh gaskets and connecting the 3in 4-bolt flanged outlets to the rest of your system, with clearance checks before final tightening. The FX-515 is supplied by MPI Automotive at an RRP of $1,293.07; contact us to confirm availability and book the bay.
