Built for the one-tonner, the MPI Automotive MKHN0257 is a 2.5in dual cat-back for the Holden Commodore VY/VZ V8 (1 Ton) running a hotdog and a rear muffler. The one-tonne ute fitment is the distinction — a cab-chassis body that routes the exhaust differently from a sedan or wagon.

What does the one-tonner fitment change?

The MKHN0257 is routed for the VY/VZ Commodore one-tonne ute (cab-chassis), which carries its exhaust along a longer, tray-back path rather than under a sedan boot. That body shape is why it's a distinct part number. The 2.5in dual pipes have to clear the one-tonner's chassis and tray, so matching the body correctly is what makes the system sit where it should.

How do the hotdog and muffler shape the note?

The hotdog is a straight-through resonator that trims resonance with little restriction, while the rear muffler is a chambered box that settles the tone by absorbing and reflecting sound. Running both on this 2.5in dual layout lets one section flow freely while the other keeps the note composed — a balanced pairing rather than a single quietening device on the V8 one-tonner.

Is it road legal?

As a cat-back, the MKHN0257 sits behind the catalytic converter and leaves the factory cat in place. Compliance depends on noise limits and your state's rules, so confirm the exact build and any NSW requirements with the workshop before fitting.

Fitment and fitting locally

It's listed to fit the Holden Commodore VY/VZ V8 one-tonner; the supplier names the V8 and the one-tonne body but not exact years, so confirm your variant with us. Oak Flats Muffler Men fits the MKHN0257 in-house across the Illawarra, clearing both 2.5in paths, the hotdog and the rear muffler along the chassis as it goes up.

Common questions

Is the MKHN0257 for the one-tonner?
Yes — it's routed for the VY/VZ Commodore V8 one-tonne ute, distinct from sedan and wagon parts. Confirm your body with the workshop.
What bore is it?
It's a 2.5in dual cat-back — two 2.5in pipes for the VY/VZ Commodore V8.
What do the hotdog and muffler do?
The hotdog trims resonance with little restriction; the rear muffler settles the note further. This build runs both.
