Holden WK WL Statesman V8 3in Dual With 1 7/8 in Extractors Muffler/Muffler.
Category: Extractors and headers


Pairing 1⅞in primaries with a dual 3in run, the MPI Automotive MKHN0305 is the higher-output extractor system listed across the Holden WK and WL Statesman V8. Twin mufflers finish the run, making this the big-primary, twin-silenced build in the family.
Primary tube size is an application choice. The 1⅞in primaries on the MKHN0305 favour higher-rpm, higher-output V8 builds, where larger primaries keep top-end flow up rather than prioritising low-down gas speed. They merge into a dual 3in run — a generous pipe per bank — finished with two mufflers. That combination of big primaries, twin 3in pipes and double silencing is what defines this WK-WL Statesman part.
The MKHN0305 runs a muffler-muffler arrangement — two mufflers in the run — for more silencing and a more settled note despite the larger primaries and bore. The extractors ahead of them replace the factory cast manifolds with tubular runners off each cylinder, a header set per bank. It is the breathing change at the head, paired here with a quieter-biased back half, working as part of the complete exhaust.
The MKHN0305 is listed to fit the Holden WK and WL Statesman V8; confirm the exact build with the workshop before ordering. The 1⅞in primary and 3in figures define the part, and material is not published by the supplier, so construction is confirmed on order.
Oak Flats Muffler Men fits 1⅞in dual extractor systems like the MKHN0305 in-house across the Illawarra. The job means dropping both factory manifolds, fresh gaskets, and routing twin 3in pipes with both mufflers under the Statesman. Supplied by MPI Automotive at $4,893.86 AUD; send your details and we will confirm fitment and book the bay.
