The MPI Automotive SSMBM378MF-R8113 is a dual centre muffler for the Holden VY–VZ 5.7L V8 1-Tonne Crewman ute. As the mid-system muffler it controls the note from the centre of the run, carrying both sides through together on the Crewman's tray-back layout.

What does the dual centre muffler do on the Crewman?

This is the centre quietening stage, run as a dual layout. A chambered/absorptive muffler in the middle of the system softens the note before it reaches the rear, taking the edge off resonance through the centre of the ute. The dual arrangement keeps both sides flowing while the muffler body does the quietening. It's the centre component specifically — not a full system and not a rear muffler — so it pairs with whatever front and rear pipework the Crewman is running. On a 1-Tonne ute the centre run shares space with the chassis and tray, so the routing matters.

Which Holden is it listed for?

It's listed to fit the Holden VY–VZ 5.7L V8 in the 1-Tonne Crewman ute. That's the tray-back, cab-chassis-derived Crewman rather than the sedan or wagon, so the centre routing and length are specific to that body. Because the VY and VZ ran across several years, confirm your exact model and the centre hanger arrangement with the workshop before ordering so the pipework and mounts line up on your truck.

Is it road legal?

This is a centre muffler only — it doesn't include or delete the catalytic converter, so the cat-delete off-road rules don't apply to this part. The finished note depends on the whole system; confirm the in-service result and any state requirements with the workshop before fitting.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Crewman centre mufflers in-house across the Illawarra, checking the dual feeds mate cleanly and the body clears the floor, chassis and tray. The SSMBM378MF-R8113 carries a published RRP of $1,170.76; send your build and we'll confirm fitment and book the bay.
