The MPI Automotive MKHN0299 is a 2.5in dual extractor-and-exhaust package listed to fit the Holden WK and WL Statesman V8. It uses a twin-muffler layout, so it's a header-back overhaul rather than a tailpipe swap.

What does this extractor system cover?

This is a header-back package for the WK and WL Statesman. It starts at the cylinder heads with extractors and runs a 2.5in dual exhaust through two mufflers in series. The factory cast manifolds and original pipework both come out, replaced as one matched MKHN0299 kit. The dual layout carries two pipes back along the long-wheelbase floor, and the two-muffler arrangement is the quieter of the muffler options MPI lists for this car.

What's an extractor and what does it change?

Extractors are tuned-length headers that replace the restrictive cast manifolds the V8 ships with. Each cylinder getting its own primary tube before the merge lowers back-pressure and helps the engine clear spent gas. The honest trade-offs: headers live in the hottest part of the bay, fit slower than a bolt-on muffler, and change the note. On the long Statesman the extractors feed a 2.5in dual run sized to flow as a matched set.

Will it suit my WK or WL Statesman?

It's listed to fit the Holden WK and WL Statesman V8. Because an extractor system is tied to the specific body and driveline, the exact build matters: send your Statesman's details and the workshop will confirm fitment before anything is ordered.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits MPI extractor packages like the MKHN0299 in-house across the Illawarra. The work means removing the factory manifolds, fitting the extractors, then hanging the 2.5in dual twin-muffler run and checking clearances along the longer floor of the Statesman. At an RRP of $4,122.28 it's a special-order set, so we confirm fitment and lead time with you before booking the bay.
