The MPI Automotive MBM380WOM is a dual centre assembly built without a muffler, listed to fit the Holden VZ 6.0L V8 Crewman. It's the muffler-delete centre section — straight pipe where the factory silencer sat — for owners chasing a freer-flowing, louder mid-section.

What does 'without muffler' mean here?

This is a centre assembly with no silencer in it: the gas passes straight through instead of routing through a chambered muffler. The result is a louder, harder note than the muffled version and less restriction in the middle of the system. It's a deliberate sound-and-flow choice rather than a quiet replacement.

Why a dual centre assembly?

The 6.0L Crewman runs a twin layout through the centre, so the MBM380WOM is supplied as a dual assembly to suit both runs. Doing the centre section as one matched assembly keeps the routing tidy and the note even side to side. It's built for a 2in bore per the supplier's spec.

Will it suit my VZ Crewman?

It's listed to fit the Holden VZ 6.0L V8 Crewman. Feed data isn't perfect, so confirm your exact build and rear layout with the workshop before ordering — a muffler-delete changes the note noticeably, so it's worth a conversation first.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this centre assembly in-house across the Illawarra. We check the assembly mates to your existing front and rear sections, set hangers and clearances, and talk through the louder result on the hoist. The MPI RRP is $562.87; we'll confirm stock and lead time when you book.
