Sized for the long-wheelbase WH Statesman, the MPI Automotive MKHN0415 is a 3in dual system with 1-3/4in primary extractors, listed to fit the WH Statesman V8. A hotdog and rear muffler shape the note on the big Holden's longer floor.
What does the WH Statesman platform mean for routing?
The WH Statesman rides a longer wheelbase than a standard Commodore, so its exhaust runs a longer path under a stretched floor. The MKHN0415 is built for that platform — a 3in dual layout routed to suit the Statesman's length, with the 1-3/4in extractors at the front. It's the header-back route for a WH owner who wants the V8 to breathe through a full dual system matched to the long body.
What does 1-3/4in primary tubing suit?
The 1-3/4in primaries keep exhaust-gas speed up for low-down and mid-range response on a street-driven V8, rather than the larger bore a high-rpm build wants — sensible for a heavier long-wheelbase car driven on the road. They're sized to the 3in dual pipework so the system flows as a set off the cylinder heads through to the rear.
What's an extractor, and what's the back end?
Extractors are tuned-length headers replacing the restrictive cast manifolds the WH V8 wore from the factory, giving each cylinder its own primary tube before the merge to cut back-pressure and aid scavenging. The honest trade-offs: they sit in the engine-bay heat zone, take labour to fit, and change the note. The back end runs a hotdog resonator to tidy the mid-range and a rear muffler for the main silencing.
Will it suit my WH Statesman, and what's the fitting?
It's listed to fit the WH Statesman V8; send your build and Oak Flats Muffler Men will confirm it before ordering. Fitting at our Illawarra workshop means removing the factory manifolds, hanging the 1-3/4in extractors, then routing the 3in dual pipework through the hotdog and rear muffler with clearance checks along the longer floor. At an RRP of $4,425.30 it's a special-order set, so we confirm fitment and lead time first.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Is this matched to the WH Statesman specifically?
- Yes — it's listed for the WH Statesman V8, with the 3in dual routing shaped for that long-wheelbase body. Confirm your exact build with the workshop before ordering.
- Why 1-3/4in primaries?
- On a street V8 they keep gas speed up for low-down and mid-range response, matched to the 3in dual pipework. We have no dyno data to quote.
- Is it a full system or just headers?
- It's a header-back system: 1-3/4in extractors plus 3in dual pipework with a hotdog and rear muffler, supplied as one matched MKHN0415 kit.
