The MPI Automotive MKHN0127 is a 3in dual extractor and exhaust package listed to fit the V8 Holden Commodore sedan across the VT to VZ series, running 1 7/8in primaries into a twin-muffler rear.

What's in this 3in dual package?

This is the headers-plus-system end of the catalogue rather than a tailpipe swap. It pairs 1 7/8in extractor primaries with a 3in dual exhaust and finishes through two mufflers, so it covers the run from the heads back. The 1 7/8in primary size is the largest in this Commodore extractor range, matched here to the 3in dual pipework for the V8.

What do extractors actually change?

Extractors replace the cast factory manifolds with tubular primaries that give each cylinder a longer, smoother path to merge. The trade-off is honest: they sit lower and run hotter than a stock manifold, take longer to fit, and on a road car the rest of the system and tuning matter as much as the headers themselves. This kit addresses that by supplying the matched 3in dual pipework and mufflers alongside the extractors.

Will it suit my VT–VZ Commodore?

It's listed to fit the V8 sedan across the VT, VU, VX, VY and VZ generations. That's a broad span of one platform, so the safest path is to confirm your exact build, engine and rear setup with the workshop before ordering — listing data covers the family, not every running change.

What does fitting involve at the workshop?

Oak Flats Muffler Men supplies and fits extractor packages like this in-house across the Illawarra. We check header-to-chassis clearance, confirm the dual layout suits your floor and rear, and book the bay once the fitment is verified.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

What primary size does the MKHN0127 use?

Does it fit every VT to VZ Commodore?
It's listed to fit the V8 sedan across that family. Confirm your exact variant with the workshop before ordering, as feed data covers the platform rather than every build.
Is this just the headers?
No — it's a 3in dual package with the extractors plus matched pipework and two mufflers.
