The MPI Automotive SSMBM525MF is a 3in centre muffler listed to fit the Nissan Navara D40 and D23. It works mid-system — the centre stage that carries the main quietening before the rear of the ute.

What does a centre muffler do?

A centre muffler sits between the front pipe and the tail and does most of the silencing with internal chambers, settling the note before it reaches the back of the system. On the Navara it's the mid-run box that keeps the daily-driver tone civil, and because it's the centre box it pairs with whatever front and rear sections the ute is running rather than being a complete system on its own.

Why one part across the D40 and D23?

It's listed for both the D40 and the later D23 Navara, which share enough of their centre-section layout for the single 3in muffler to cover both generations. Confirm which you have so the mid-system pipework lines up — the two generations span a long run of the ute, so the build still has to be checked rather than assumed from the model.

Why 3in?

At 3in this is sized for an upgraded Navara exhaust rather than the factory pipe, matched to the centre position so the quietening happens mid-run on the turbo-diesel ute. The larger bore suits a system that's been opened up upstream, and it leaves the rear free to be tuned separately for the exit.
