What pipe size is the MBM557MF?

3in, matched to the D22 turbo-diesel. It's the rear muffler, the last silencer before the tailpipe.

Which engines does it cover?

It's listed for the Nissan Navara D22 with both the 2.5L and 3.0L turbo-diesel engines. Confirm your exact build with the workshop before ordering.

Is it a full exhaust?

No — it's the rear muffler only, replacing the back silencer section rather than the whole system.

Built at 3in, the MPI Automotive MBM557MF is a rear muffler listed to fit the Nissan Navara D22 with the 2.5L and 3.0L turbo-diesel engines. The 3in bore sets it apart — a freer-flowing rear silencer matched across both D22 diesel capacities.

Why a 3in rear muffler?

The 3in bore suits a turbo-diesel ute that's been opened up elsewhere, keeping the rear section flowing rather than choking it down. As the rear muffler, it's the last silencer before the tailpipe and sets the final note. Replacing it changes the rear silencing without touching the front or centre pipework — a targeted refresh for a worn or restrictive back end on the D22.

Why does it cover both the 2.5L and 3.0L?

The D22 Navara ran both 2.5L and 3.0L turbo-diesel engines that share enough of the rear exhaust layout to take a common 3in rear muffler. One part number across both diesel capacities is the practical appeal of this listing rather than an engine-specific section.

Will it suit my Navara D22?

It's listed to fit the Nissan Navara D22 2.5L and 3.0L turbo-diesel. D22s came in several specs over a long run, so send your exact build to the workshop and we'll confirm the rear hanger points and tailpipe routing before ordering. We treat the listing as a guide and check the ute on the hoist first.
