The MPI Automotive MKHN0291 is a 2.5in extractor and exhaust package listed to fit the Holden WH Statesman V8. It teams tubular extractors with 2.5in system pipework run as a dual setup and finishes with a muffler and tailpipe, swapping out the cast factory manifolds and the gear behind them.

What does this extractor package cover?

Extractors, also called headers, replace the cast factory exhaust manifolds with separate tubular runners off each cylinder, then feed into the rest of the system. The MKHN0291 is a full run rather than the headers on their own: tubular extractor primaries step into 2.5in pipework, split as a dual layout, and end in a muffler and tailpipe. It changes the exhaust side of the engine — how spent gas leaves the heads — not anything inside the engine.

What do the size and end setup change?

Sized at 2.5in, the 2.5in bore sets the diameter the rest of the exhaust mates to behind the extractors, and this one finishes with a muffler and tailpipe. The aim is to let a V8 like this breathe out with less restriction than the cramped cast factory manifolds, while the muffler arrangement keeps the note in check.

Will it suit my Holden WH Statesman V8?

The MKHN0291 is listed to fit the Holden WH Statesman V8. Read that as "listed to fit", not a guarantee: extractors are a significant fitment and have to match the specific platform, body and engine. Confirm your exact build with the workshop before ordering, since series, body style and driveline details decide whether this set drops in cleanly.
