Is the MKNI0117 legal to register 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.

How does the hotdog compare to a bare pipe?

It softens the note while staying free-flowing, so it's more controlled than a no-muffler delete but still an open, off-road build.

Which Navara does it fit?

The Nissan Navara D22 2.5L. Confirm your exact build with us, as the years aren't published.

The MPI Automotive MKNI0117 is a cat-deleted build for the Nissan Navara D22 2.5L that retains a hotdog resonator — the off-road option that keeps a measure of silencing in the middle. Deleting the cat makes it off-road use only.

Is it road legal?

No. The MKNI0117 deletes the catalytic converter on a road-relevant exhaust, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. That's a hard limit — the cat is emissions hardware the ute carried when registered, and this build removes it. We'll point out where it's appropriate before you commit.

What does the hotdog do without a cat?

A hotdog is a compact straight-through resonator — a perforated core packed with absorptive material — so it eases the harshest edge off the note while keeping flow open. On this cat-delete D22 2.5L it gives a freer system than a cat-and-muffler build, but the hotdog stops it being a completely bare pipe. It's the middle option in the off-road set: more open than a silenced exhaust, more controlled than a no-muffler delete. We can't put a number on the volume.

Will it suit my Navara D22 2.5L?

It's listed to fit the Nissan Navara D22 with the 2.5L engine. The supplier doesn't publish years for this listing, so confirm your exact build and year with the workshop before ordering instead of assuming a range the record doesn't carry.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the MKNI0117 in-house across the Illawarra, for off-road use. We position the hotdog clear of the chassis, set the hangers and confirm the application suits how the ute is used before booking the bay.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
