The MPI Automotive SSMKHN0256 is the quietest of the 1-ton family — a 2.5in dual cat-back finished through twin chambered mufflers for the VY–VZ Holden Commodore V8 1-tonner. Two mufflers keep the note subdued on a working body.

What do the twin mufflers give the 1-tonner?

Running a muffler at each stage, this build quietens through baffled chambers that reflect and absorb sound rather than letting it run straight through. On a 1-ton body used for work, that keeps the cabin note restrained while the 2.5in dual pipework still relieves the factory rear restriction.

Why is the 1-ton routing specific?

The Commodore 1-tonner sits on a longer, ute-derived chassis, so the rear floor, hangers and exhaust path differ from the sedan and wagon. The SSMKHN0256 is shaped to that chassis, with a 2.5in bore matched to a stock or lightly worked V8.

Will it suit my VY–VZ 1-tonner?

It is listed to fit the Holden Commodore V8 1-ton across VY–VZ. Confirm your exact build with the workshop before ordering, as the 1-ton body does not share a rear section with the sedan or wagon.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this system in-house across the Illawarra, checking hanger alignment, the tailpipe exit and clearance along the long 1-ton floor before sign-off. The listed RRP is AUD 2,186.72, and the part can be special-ordered through MPI Automotive when it is not in stock. Send your build details and we will book it in.

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

Common questions

Is the SSMKHN0256 the quietest 1-ton option?
Among the 1-ton cat-backs it runs twin chambered mufflers, the most subdued configuration. We describe the note from the design; no decibel figures are published.
Does it keep the catalytic converter?
As a cat-back it replaces the rear section from the cat back. Catalytic converter status is not published in the supplier record; the workshop confirms on inspection.
