The MPI Automotive MKHN0258 is a 2.5in dual cat-back for the Holden Commodore VY/VZ V8 one-tonner, run without a muffler. The muffler-delete (WOM) layout is the headline — the most open of the silencing options for this body.
What does 'without muffler' mean here?
The MKHN0258 runs the dual 2.5in system through to the tail without a chambered muffler in the silencing position — a straight path where the box would normally sit. That makes it the freest-flowing and loudest of the one-tonner options, with the hardest note, because there's no absorptive body to soften it. It suits an owner who wants minimal restriction across the cab-chassis floor and accepts the volume. We can't quote a sound figure; hear a comparable fit first.
What does the 2.5in dual bore suit?
At 2.5in the bore keeps gas speed up for low-down response on the V8, and the dual cat-back splits into two pipes from the catalytic converter rearward across the one-tonner's chassis. Even without a muffler, the bore stays at the milder size rather than stepping up. It's the open build for the cab-chassis body. The honest measure of the note is hearing a comparable VY/VZ one-tonner fit.
Will it suit my VY-VZ one-tonner?
It's listed to fit the Holden Commodore VY and VZ V8 one-tonner — the cab-chassis body, which routes differently to the wagon, sedan and ute. The one-ton chassis sets the run. Confirm your exact build with the workshop before ordering.
How do we fit it in Illawarra?
Oak Flats Muffler Men supplies and fits the MKHN0258 in-house across the Illawarra. Because there's no muffler to absorb resonance, we pay attention to how the open dual run sits against the chassis and hangers. Bring the one-tonner in and we'll confirm fitment and book the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
