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


The MPI Automotive MKHN0306 is a 3in extractor and exhaust package listed to fit the Holden WK/WL Statesman V8. It pairs 1-7/8in tubular extractors with 3in system pipework and a hotdog resonator and a rear muffler, replacing the cast factory manifolds and the gear behind them.
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 MKHN0306 is a full run rather than the headers alone: 1-7/8in primaries step into 3in pipework and finish with a hotdog resonator and a rear muffler. 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.
The tail side here uses a hotdog resonator and a rear muffler. A hotdog is a compact straight-through resonator that takes some edge off the note without the volume of a full muffler box; behind it the rear muffler does the main silencing. Sized at 3in, with 1-7/8in primaries off the heads, the MKHN0306 aims to free up flow past the cast manifolds while keeping the note civil, not raucous.
The MKHN0306 is listed to fit the Holden WK/WL 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.
Oak Flats Muffler Men fits extractor packages like the MKHN0306 in-house across the Illawarra. The job means good access to drop the cast manifolds off the heads, fresh gaskets, and matching the 3in pipework and hotdog resonator and rear muffler back along the car. Supplied by MPI Automotive at $4,836.82 AUD; this is a made-to-order set, so send us your Holden WK/WL Statesman V8's build details and we'll confirm the fit and book the bay.
