Is the MKNI0096 road legal in NSW?

No — it deletes the catalytic converter on a turbo-back system, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use.

It's a 3in turbo-back, sized to suit the NP300 Navara's turbo-diesel.

Does it have a muffler?

Yes — it finishes with a muffler to keep the note controlled, though it still runs without a catalytic converter.

The MPI Automotive MKNI0096 is a 3in turbo-back exhaust for the Nissan NP300 Navara, built without a catalytic converter and finished with a muffler. Because it deletes the cat on a road-relevant system, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use.

What does a turbo-back without cat mean for road use?

A turbo-back replaces the exhaust from the turbo outlet all the way back — a longer span than a cat-back. This version runs without a catalytic converter, so it removes the emissions hardware the NP300 left the factory with. That makes it not ADR 79/04 compliant for road registration in NSW; it's for off-road use, and we won't soften that. It suits competition, private-property or off-road applications where road compliance isn't required.

What does the 3in bore and muffler give?

At 3in this turbo-back is sized for the NP300's turbo-diesel, the bigger-bore step where a turbocharged ute tends to free up off-boost restriction. It finishes through a muffler, so the note stays more controlled than a straight-through tailpipe would — but the cat delete is the defining feature, not the silencing.

Will it suit my Nissan Navara NP300?

It's listed to fit the Nissan NP300 Navara. The listing doesn't specify the engine here, so confirm your exact NP300 build and turbo arrangement with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this turbo-back in-house across the Illawarra. Because it's a no-cat off-road system, we'll confirm the intended use, the build and clearances on your NP300 before booking the bay.
