Large 1⅞in primaries feeding a 3in dual, finished through a rear muffler and tailpipe — that combination is the MPI Automotive SSMKHN0237 for the VU-VY-VZ V8 ute. It pairs the bigger-bore extractor option with a single muffler-and-tailpipe rear rather than a silencer on each bank.

What do the 1⅞in primaries change?

Primary tube size sets the character. At 1⅞in the SSMKHN0237 leans toward higher-rpm, higher-output builds, where larger primaries help the V8 keep breathing as flow demand rises — the bigger-bore end of the extractor range rather than the smaller primaries tuned for low-down gas speed on a stock motor. It's a spec chosen when the engine is built to use it.

How is the rear arranged?

The 3in dual runs back to a single rear muffler and out a tailpipe, rather than a muffler each side. That keeps the back end lighter while still silencing the note — a different rear treatment from the twin-muffler and hotdog builds in this family, paired here with the large-primary, 3in plumbing.

What's in the package?

It's a complete extractor-back system. The 1⅞in tube-and-merge extractors replace the cast factory manifolds at the heads — the main breathing restriction on these V8s — then the 3in dual carries the gas back through the rear muffler and out the tailpipe. The upgrade runs from the engine all the way to the tail.

How is fit confirmed at our Illawarra workshop?

Oak Flats Muffler Men fits MPI extractor systems in-house across the Illawarra. The SSMKHN0237 is listed to fit the VU-VY-VZ V8 ute; because the 1⅞in/3in sizing is the higher-rpm-leaning spec and it's a major spend, we confirm your exact series and that this suits your build before ordering. Send your build and we'll book it in.

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

Common questions

Who are the 1⅞in primaries for?
They suit higher-rpm, higher-output builds — the larger-bore extractor option. For a stock street tune the smaller primaries hold gas speed up better; confirm what suits your engine with the workshop.
What's the rear setup?
A 3in dual into a single rear muffler and tailpipe, rather than a muffler each side — a lighter back end that still damps the note.
