Running a centre hotdog rather than a full muffler, the MPI Automotive MKIZ0021 is a turbo-back listed to fit the Isuzu D-Max 3.0L from 2020 on, and it keeps the factory catalytic converter. The hotdog is the distinguishing part of this build: a compact straight-through resonator that takes the edge off without the volume drop of a chambered muffler.
What does the centre hotdog change?
A hotdog is a short, straight-through resonator — gas flows through a perforated core rather than being bounced through chambers. On the MKIZ0021 it sits in the centre of the run in place of a larger muffler, so it trims harshness and drone while letting the diesel breathe. The result is a freer-flowing turbo-back with a more present note than a fully muffled system, without going to a bare straight pipe.
Is the MKIZ0021 road legal?
This is the with-cat configuration, so the factory catalytic converter stays in place — the emissions hardware the D-Max left the factory with is retained. That's the part that matters for road compliance on a diesel ute. Confirm the exact build and any state requirements with the workshop before fitting, but keeping the cat is what makes this the road-minded option in the family.
What's a turbo-back and where does it sit?
A turbo-back replaces everything from the turbo outlet rearward, which is the longest single span you can do short of a full custom system. On a 3.0L diesel D-Max it's the upgrade that frees the most pipework while keeping the cat. The MKIZ0021 has a published RRP of $2,302.84.
Will it fit, and who fits it?
It's listed to fit the Isuzu D-Max 3.0L from 2020 on; send us your series and year and we'll confirm before ordering. Oak Flats Muffler Men supplies and fits MPI turbo-back systems in-house across the Illawarra, checking hotdog placement and clearances on the hoist.

Common questions
- What's the difference a hotdog makes versus a muffler?
- A hotdog is a compact straight-through resonator, so it flows more freely and gives a more present note than a chambered muffler, which quietens by absorption and reflection. The MKIZ0021 uses the hotdog in the centre of the run.
- Does the MKIZ0021 keep the catalytic converter?
- Yes — this is the with-cat turbo-back, so the factory catalytic converter stays in place.
- Does it fit the D-Max from 2020?
- It's listed to fit the Isuzu D-Max 3.0L from 2020 on. Confirm your exact variant with the workshop before ordering.
