The MPI Automotive MBM422WOM is a 3in centre section supplied without a muffler — a straight-through delete pipe listed to fit the Mitsubishi Triton (ML, MN, MQ), Challenger PB and Pajero Sport with the 2.5L and 3.2L engines. The without-muffler design is the whole point: it replaces the factory centre silencer with open pipe.

What does a without-muffler centre do?

Rather than a chambered silencer, the MBM422WOM is a straight-through centre pipe — it removes the factory mid-system muffler and runs clear pipe in its place. That frees the centre of the system and gives a louder, harder note than the standard centre muffler, leaving the rear silencer to do the remaining quietening. It's the choice for owners who want more sound from the middle of the run without changing the rear.

Why the 3in bore across these Mitsubishis?

At 3in the centre pipe is sized for the 2.5L and 3.2L turbo-diesels in this family, carrying their flow without becoming a mid-system pinch point. The same section is listed across the Triton, Challenger and Pajero Sport because they share the underbody and driveline architecture of the era.

Will it fit my Triton, Challenger or Pajero Sport?

It's listed to fit the Triton ML/MN/MQ, Challenger PB and Pajero Sport in 2.5L and 3.2L form. That's a broad family, so send your exact model, engine and build and we'll confirm the centre length and hanger points before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits the MBM422WOM in the centre section in-house, clamping or welding it in and aligning it clear of the chassis. Book your Mitsubishi in and we'll confirm the fitment against your build.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
