Does the MKNI0112 keep the cat?

Yes — it retains the factory catalytic converter and deletes the rear muffler only.

Will it be louder than stock?

Removing the rear muffler lets more of the diesel note through than the factory tail. We can't quote a sound level — hear a comparable fit at the workshop.

The MPI Automotive MKNI0112 keeps the catalytic converter and deletes the rear muffler on the Nissan Navara D22 3.0L — the cat-retaining build that opens up the tail without touching the emissions hardware.

What does keeping the cat but dropping the muffler do?

On the 3.0L this build leaves the front of the system as the ute left the factory, catalytic converter included, and removes only the rear muffler. The emissions component a registered diesel relies on is retained, while the last silencing stage is gone — letting more of the 3.0L's note carry through to the tail. It's the choice for owners chasing a fuller sound who want the cat kept, which separates the MKNI0112 from the cat-delete builds in the family. We can't quote a sound level.

Will it suit my Navara D22 3.0L?

It's listed to fit the Nissan Navara D22 with the 3.0L engine. The supplier doesn't publish years for this listing, so confirm your exact build, year and rear hanger layout with the workshop before ordering rather than assuming a span the record doesn't give.

Is it road legal?

The MKNI0112 keeps the catalytic converter, the emissions hardware most relevant to keeping a diesel ute registered, so that equipment stays as delivered. Deleting the rear muffler does change the factory silencing, and noise compliance is judged on the whole vehicle — confirm the current NSW requirements and your intended use with the workshop before fitting.
