Does the SSMKNI0116 keep the cat?

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

Will it be louder without the muffler?

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

Which engine is it listed for?

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

Keeping the catalytic converter but running no rear muffler, the MPI Automotive SSMKNI0116 is the cat-retaining, muffler-deleted exhaust listed to fit the Nissan Navara D22 2.5L. It leaves the emissions hardware in place while opening up the tail.

Cat in, muffler out — what does that mean?

This build keeps the catalytic converter — the emissions component a registered diesel ute relies on — but deletes the rear muffler. So the front of the system stays as the D22 left the factory, while the rear loses its silencing stage. The result on the 2.5L is a more present note from the tail without removing the cat. It's the option for owners who want a fuller sound but want the catalytic converter retained, unlike the cat-delete builds in the same family.

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 layout with the workshop before ordering rather than guessing a span the record doesn't give.

Is it road legal?

The SSMKNI0116 keeps the catalytic converter, which is the emissions hardware that matters most for road registration on a diesel ute. Retaining the cat leaves that equipment in place; however, deleting the rear muffler changes the vehicle's 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.
