The MPI Automotive MKNI0088 is a cat-and-DPF-replacement section for the Nissan Navara D40 2.5L auto (2005–2007), finished with a rear muffler. It targets the emissions-component section of the system on the early auto D40 specifically.

What does a cat-and-DPF replacement cover?

This part replaces the catalytic-converter and diesel-particulate-filter section of the D40's exhaust and carries through to a rear muffler. It's an emissions-hardware section rather than a full system, so it addresses the part of the exhaust where the cat and DPF sit. Anything touching emissions equipment on a diesel has compliance implications, so the intended use and any state requirements must be confirmed before fitting.

Why the 2.5L auto and 2005–2007 specifics?

The MKNI0088 is listed for the D40 Navara with the 2.5L engine, the automatic transmission, and the 2005–2007 build window. Those specifics matter on the D40 because driveline and model-year changes alter the section layout, so this is pitched at that early-auto combination rather than the D40 range as a whole.

Will it suit my Nissan Navara D40?

It's listed to fit the Nissan Navara D40 2.5L auto from 2005 to 2007. Confirm your exact transmission, year and existing emissions setup with the workshop before ordering, since this is an emissions-section part where the precise build is decisive.
