For the WH Statesman, the MPI Automotive MKHN0290 runs a dual 2.5in layout with a hotdog resonator. Listed to fit the Holden WH Statesman V8, it carries twin 2.5in pipes — one per bank — through the hotdog and into the muffler.

What does the dual 2.5in setup do?

A dual layout gives the WH's V8 a pipe for each bank rather than collecting both sides into one, and the MKHN0290 carries that as twin 2.5in runs from the extractors back. A hotdog — a compact straight-through resonator — sits in the run to take the edge off the note ahead of the muffler. Paired pipes, a resonator and a muffler are the character of this WH Statesman part.

Where do the extractors come in?

Extractors replace the WH's cast factory manifolds with tubular runners off each cylinder, a header set per bank on the V8, each merging into its own 2.5in pipe. That tube-and-merge layout clears gas more cleanly than the cast castings and on this part feeds the resonated dual run. It is the breathing change at the head, working as part of the complete exhaust.

Will it suit my WH Statesman V8?

The MKHN0290 is listed to fit the Holden WH Statesman V8; confirm the exact build with the workshop before ordering. The 2.5in figure sets the pipe size for both banks, the hotdog is part of the run, and material is not published by the supplier, so construction is confirmed on order.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits dual extractor systems like the MKHN0290 in-house across the Illawarra. The job means dropping both factory manifolds, fresh gaskets, and routing two 2.5in pipes with the hotdog and muffler under the WH. Supplied by MPI Automotive at $4,094.57 AUD; send your details and we will confirm fitment and book the bay.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
