Does the MKNI0116 keep the catalytic converter?

Yes — it retains the factory cat 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.

Which engine is it for?

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

The MPI Automotive MKNI0116 keeps the catalytic converter and deletes the rear muffler on the Nissan Navara D22 2.5L — the cat-retaining build that opens the tail while leaving the emissions hardware alone.

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, year and rear hanger arrangement with the workshop before ordering — the D22 ran several changes, and we'd rather verify than assume a span the record doesn't give.

Cat retained, muffler removed — what changes?

On the 2.5L this build leaves the front of the system as the ute left the factory, with the catalytic converter in place, and removes only the rear muffler. So the emissions component a registered diesel relies on is kept, while the last silencing stage is gone — letting more of the engine's note carry through to the tail. It's the pick for owners who want a fuller sound but want the cat retained, which separates the MKNI0116 from the cat-delete builds in the family. We can't quote a sound level.

Is it road legal?

The MKNI0116 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 assessed on the whole car — confirm the current NSW requirements and your intended use with the workshop before fitting.
