How do I know if I have the Spain build?

The D40 was built in more than one market and the plumbing differs. This one is for the Spanish-built 2.5L auto — confirm your variant with the workshop before ordering.

Can I register a D40 with this fitted?

No. It replaces the catalytic converter and DPF, so it isn't ADR 79/04 compliant for road registration in NSW and is for off-road use only.

Is it the quieter option?

It runs a rear muffler that absorbs sound, so it's the more subdued choice for the platform.

This one is the Spanish-built Nissan Navara D40 2.5L auto — the MPI Automotive MKNI0078 is listed specifically for the Spain plant variant, which matters because the D40 didn't come from a single factory. It's a DPF-and-cat replacement system with a rear muffler, replacing both emissions devices in the run.

Why is the Spain build called out?

The D40 Navara was assembled in different markets, and the exhaust plumbing and emissions hardware can vary between them — so MPI list this version for the Spanish-built 2.5L auto rather than as a one-size-fits-all part. Matching the build origin is what makes a system like this line up cleanly, which is why it's a separate listing. The rear muffler keeps the note in check by absorption, making this the quieter option for the platform.

What does replacing the DPF and cat involve?

Rather than retaining them, this system replaces the diesel particulate filter and the catalytic converter in the exhaust path. The DPF traps diesel soot and the cat handles emissions chemistry; replacing both takes that hardware out of the run, with the rear muffler then managing sound for the remaining system.

Is the MKNI0078 road legal in NSW?

No. Because it replaces the catalytic converter (and DPF) on a road-relevant exhaust path, the MKNI0078 is not ADR 79/04 compliant for road registration in NSW and is for off-road or competition use only. Removing the DPF and cat strips the emissions hardware the Navara left the factory with, and that can't be softened for registration. Ask the workshop about your options if you need to stay registrable.

Will it fit my D40, and how do you fit it?

It's listed to fit the Spanish-built Nissan Navara D40 2.5L auto. The supplier doesn't publish a year range here, so confirm your exact D40 build — and that it's the Spain variant — with the workshop before we order. Oak Flats Muffler Men supplies and fits this MPI Automotive system in the Illawarra; we'll check the routing under your Navara and talk through the off-road-only use before booking the bay.
