Is the MKNI0002 road legal in NSW?

No. It deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only.

It's built around a 3in bore — the larger-bore step for freer flow on the D22 3.0L diesel.

Does it have a muffler?

Yes. It runs a muffler to quieten the cat-less 3in pipe, so it isn't completely raw, though it remains off-road only.

The MPI Automotive MKNI0002 is a 3in exhaust listed to fit the Nissan Navara D22 3.0L, built without the catalytic converter and finished with a muffler. The cat-delete is the defining feature here: it removes the converter, so this is an off-road-only build.

What does the cat-delete mean for road use?

Because the MKNI0002 deletes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. There's no softening that — removing the cat takes out emissions hardware the D22 needs to be road-legal. We state it plainly so you can decide whether an off-road build suits your situation before ordering.

Why pair a 3in cat-delete with a muffler?

At 3in the bore is sized for freer flow on the D22 3.0L diesel, and deleting the cat removes a restriction in that path. The muffler is then doing the manners work: it quietens the system by absorption and reflection so a stripped, cat-less 3in pipe isn't unbearably harsh. It's the freest-breathing of these D22 builds, with a muffler keeping the note from being completely raw.

Will it suit my Navara D22 3.0L?

It's listed to fit the Nissan Navara D22 with the 3.0L engine. D22s vary across their production run, so confirm your exact build and year with the workshop before ordering, and weigh up the off-road-only status for your use. Listed fitment is a guide, not a guarantee.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men supplies and fits the MKNI0002 in-house. We confirm the 3in run clears the chassis, set the muffler and hangers, and talk through the off-road-only implications before sign-off. RRP is AUD 1467.68; send your D22 3.0L's spec and we'll book the bay.
