MPI Automotive Holden Commodore VE, VF all V8s, 1 7/8in, 4 - 1 Tuned, 3in Outlet Extractor.
Category: Extractors and headers


The MPI Automotive HOLH128-178 is a 1-7/8in, 4-into-1 tuned extractor set with a 3in outlet, listed to fit the Holden Commodore VE and VF with all V8 engines. It replaces the factory cast manifolds with tubular runners.
The HOLH128-178 is a tube extractor set for the VE-VF Commodore fitted with the V8. It runs 1-7/8in primaries in a tuned 4-into-1 design feeding a 3in outlet. As a V8 it has an extractor per bank, each merging four runners into one collector. The listing ties it to the VE and VF body and all V8 engines, with the primary and outlet sizes called out in the part itself.
An extractor (header) bolts to the cylinder head in place of the factory manifold. A tuned 4-into-1 design merges a bank's four runners into one collector after a set length of pipe — here 1-7/8in primaries feeding a 3in outlet — to ease back-pressure out of the head. The larger 1-7/8in primary is a step up from a 1-3/4in set and suits a V8 worked harder up top. It is the front-most and hottest part of the system, and it changes the exhaust note compared with the cast manifold.
The HOLH128-178 is listed to fit all VE and VF Commodore V8s, with 1-7/8in primaries and a 3in outlet. Confirm your exact engine and what it mates to behind the collector with the workshop before ordering.
Oak Flats Muffler Men fits Commodore V8 extractors in-house across the Illawarra. The swap means removing the cast manifolds, fitting fresh gaskets, and aligning the 3in outlet to the system behind with clearance checks before final tightening. The HOLH128-178 is supplied by MPI Automotive at an RRP of $1,494.17; contact us to confirm fitment and book the bay.
