Is the SSMKNI0004 road legal?

No — it's supplied without a catalytic converter, so it's not ADR 79/04 compliant for road registration in NSW and is for off-road use only.

It's 3in — the larger bore, sized to flow more freely on an off-road or modified D22 2.5L.

Will it fit my D22 2.5L?

It's listed for the Nissan Navara D22 2.5L. Confirm your exact build and intended use with the workshop.

The MPI Automotive SSMKNI0004 is a 3in exhaust for the Nissan Navara D22 2.5L, supplied without a catalytic converter and with a muffler. As a cat-delete system on a 3in bore it's for off-road use only, sized for the bigger flow a delete suits.

Is it road legal?

No. The SSMKNI0004 is supplied without a catalytic converter, so on a road-going diesel it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. Deleting the cat removes the emissions hardware the D22 2.5L needs to be road-compliant — there's no softening that. Talk to the workshop about your intended use before ordering.

What does the 3in bore suit?

At 3in this is the larger-bore exhaust, sized to flow more freely than a smaller pipe — the diameter that suits an off-road or modified D22 2.5L where the cat has been removed. It runs a chambered muffler to keep the note settled rather than open, so it's the bigger-bore breathing with restrained tone, for off-road use.

Will it suit my Navara D22 2.5L?

It's listed to fit the Nissan Navara D22 2.5L. The D22 ran across several builds, so confirm your exact variant with the workshop before ordering. We'll check the hanger layout and clearance against your vehicle.
