Is the SSMKNI0009 for the automatic D40?

Yes — it's listed for the Nissan Navara D40 2.5L auto built 05–07. The manual has its own separate listing.

Does it retain the catalytic converter?

Yes. It's a with-cat system finishing in a rear tailpipe, so the factory catalytic converter stays in place.

The MPI Automotive SSMKNI0009 is the automatic-transmission, with-cat exhaust listed to fit the Nissan Navara D40 2.5L (05–07), ending in a rear tailpipe. At an indicative RRP of 3543.98 AUD, it's the auto counterpart to the early-D40 manual tailpipe system.

What separates this auto listing from the manual one?

The defining detail here is the automatic gearbox: the D40 auto routes its exhaust differently to the manual, so MPI Automotive lists it under its own part number, the SSMKNI0009. It shares the 05–07 dating and the 2.5L engine with the early-D40 family, but the transmission is what you confirm first. Diameter and material aren't published, so we don't quote them.

Does keeping the cat affect road use?

Because the SSMKNI0009 retains the catalytic converter, the emissions hardware the D40 left the factory with stays in place — the relevant factor for road compliance on this vehicle. Final compliance still depends on your complete vehicle and the requirements in your state, so confirm the specifics with the workshop before it's fitted.

Is this the right early-D40 system for my ute?

It's listed to fit the Nissan Navara D40 2.5L auto from 05–07, finishing in a rear tailpipe rather than a rear muffler. We match the engine, the automatic gearbox and the year against your vehicle before ordering, because the listing is a starting point and feed data can be imperfect.
