The MPI Automotive MKHN0289 is a 2.5in extractor and exhaust package listed to fit the Holden WH Statesman V8. It runs 2.5in system pipework off the extractors and finishes with twin mufflers, replacing the cast factory manifolds and the pipework behind them.

What does this extractor package cover?

Extractors, also called headers, swap the cast factory exhaust manifolds for separate tubular runners off each cylinder, then feed into the rest of the system. The MKHN0289 is a full run rather than the headers alone: the listed primaries step into 2.5in pipework and finish with twin mufflers. It is a change to the exhaust side of the engine — how the spent gas leaves — not an internal engine part, and it does its work as part of the wider system on this long-wheelbase Holden.

What do the size and muffler setup change?

This build runs twin mufflers, which keeps the note more subdued than a hotdog-and-muffler or single-muffler setup on the same car. The system is 2.5in off the listed primaries, so the bore the rest of the exhaust mates to is set at 2.5in. The aim is to let the engine breathe out past the cast manifolds while keeping volume measured — the quieter end of the range for this platform.

Will it suit my Holden WH Statesman V8?

The MKHN0289 is listed to fit the Holden WH Statesman V8. Treat that as "listed to fit", not a guarantee: extractors are a significant fitment and need to match the specific platform, body and engine. Confirm your exact build with the workshop before ordering, since series, cab and driveline details decide whether this set drops in cleanly.

What does fitting involve at our Illawarra workshop?
