The MPI Automotive MKHN0401 is a 3in dual extractor-and-exhaust package built around 1-3/4in primary extractors, listed to fit the VY and VZ HSV V8 sedan. It runs 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: it starts at the cylinder heads with 1-3/4in primary extractors and carries through to a 3in dual exhaust running two mufflers in series. On a VY–VZ HSV V8 sedan, that means the factory cast manifolds and the original pipework both come out, replaced as one matched MKHN0401 kit. The dual layout splits the flow into two pipes, and the two-muffler arrangement is the quieter of the muffler options MPI lists for this platform.
What's an extractor and what does it change?
Extractors (tuned-length headers) replace the restrictive cast-iron manifolds the V8 left the factory with. By giving each cylinder its own primary tube before they merge, they reduce back-pressure and help the engine scavenge spent gas more cleanly. The trade-off is honest: headers sit in the engine bay heat zone, take longer to fit than a bolt-on muffler, and change the exhaust note. The 1-3/4in primary size here is matched to the 3in dual pipework so the system flows as a set.
Will it suit my VY or VZ HSV sedan?
It's listed to fit the VY and VZ HSV V8 sedan — the record names both Holden and HSV for this listing. Because it's an extractor-based system tied to a specific body and driveline, the exact build matters: send your VY or VZ details and the workshop will confirm the 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 MKHN0401 in-house across the Illawarra. Header work means removing the factory manifolds, fitting the primaries, then hanging the 3in dual twin-muffler run and checking clearances under the floor. At an RRP of $4,444.69 it's a special-order set, so we confirm the fitment and lead time with you before booking the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
