The MPI Automotive SSMBM526MF is a 3in rear muffler listed to fit the Nissan Navara D40 and D23. The rear mounting is its defining feature — it's the final silencing box before the tailpipe.

What does a rear muffler do?

A rear muffler is the last box in the system, so it sets the final tone the car leaves with and trims whatever volume the upstream pipework hasn't already. On the Navara it's the tailpipe-end stage, mounted at the back of the ute, which makes it a targeted change for owners who want to adjust the exit note without rebuilding the whole exhaust.

Why one part for the D40 and D23?

It's listed across both the older D40 and the later D23 Navara, which share enough of their rear exhaust layout for the single 3in rear muffler to cover both. Confirm which generation you have so the rear pipework matches — the two generations span a long run of the Navara, so the build still has to be checked rather than assumed from the badge.

Why 3in?

At 3in this is sized for an upgraded Navara exhaust rather than the factory pipe, suited to the turbo-diesel where freeing up the back of the system is the usual aim. The larger bore matches a system that's been opened up upstream, and the rear position lets it set the final note without touching the rest of the run.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits rear mufflers like this in-house across the Illawarra. We check the rear hangers, the clearance over the axle and the tailpipe exit on the hoist, then book the bay once your build is confirmed. The RRP is listed, and we'll confirm the part suits your existing system before ordering it in.
