Can I register a Navara with the MKNI0118 fitted?

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.

This version runs no rear muffler, giving the most open path in the family — suited to an off-road ute, not a quiet daily.

Which engine does it fit?

The Nissan Navara D22 2.5L. Years aren't published, so confirm your exact build with us first.

With the catalytic converter deleted and no rear muffler, the MPI Automotive MKNI0118 is the most open exhaust in the Navara D22 2.5L set. The cat-delete means it's strictly an off-road build.

Is it road legal?

No. The MKNI0118 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. We state that plainly — the cat is emissions hardware the ute was registered with, and this build removes it along with the rear muffler. We'll explain where it can legitimately be used before you order.

What's the appeal of deleting both?

Removing the catalytic converter and the rear muffler leaves the least restrictive path this part offers on the D22 2.5L — nothing in the system absorbing or reflecting sound, and no cat in the front section. That gives the most natural diesel note and the freest flow, which is why it's chosen for off-road or competition utes where the cat and silencing aren't required. It is not a setup for a registered, daily-driven vehicle.

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 rather than assuming a span the record doesn't state.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the MKNI0118 in-house across the Illawarra, for off-road use. We confirm the application first, then set the hangers for a muffler-delete tail and check clearance along the chassis before booking.

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