The MPI Automotive SSMKHN0253 is built for the One Tonner — the cab-chassis VY-VZ V8 with a longer wheelbase and a tray-back rear that a standard ute doesn't share. It's a 2.5in dual extractor-and-exhaust package, muffler each side, listed to fit that 1-ton body.

Why a One Tonner-specific system?

The VY-VZ One Tonner sits on a stretched cab-chassis platform with its own rear-end layout and ride height for load carrying, so the dual pipework, hanger points and rear muffler placement differ from a regular ute. The SSMKHN0253 is listed against the 1-ton body for that reason — same V8, but the section behind the cab is routed for the longer working chassis.

What does the package replace?

It's a full extractor-back system rather than headers alone. Tube-and-merge extractors take the place of the cast factory manifolds at the heads — the main breathing restriction on these Holden V8s — and the system then runs as a matched 2.5in dual with a rear muffler each side. You're upgrading the exhaust from the engine all the way back.

What's the 2.5in dual, muffler-each-side character?

A 2.5in dual keeps gas speed up across both banks for low-down and mid-range response while flowing more than the factory plumbing — sensible for a vehicle built to carry weight. With a muffler each side rather than a hotdog or open tail, the SSMKHN0253 aims for a fuller note that stays workmanlike, not raucous, which suits a One Tonner that earns its keep.

How is fit confirmed at the Illawarra workshop?

Oak Flats Muffler Men supplies and fits MPI extractor systems in-house across the Illawarra. Because the 1-ton platform differs from the standard ute and this is a major-spend item, we confirm your VY or VZ series, the cab-chassis layout and rear hanger arrangement before ordering. Send your build and we'll book the bay.

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

Common questions

Is the SSMKHN0253 different from a standard Commodore ute system?
Yes — it's listed for the VY-VZ One Tonner, whose longer cab-chassis platform routes the rear section differently from a regular ute. Confirm your body with the workshop.
Does it include the extractors and the exhaust?
It's a complete extractor-back package: tube extractors at the heads plus the 2.5in dual exhaust and rear mufflers.
