The SSMBM378MF is the 2in dual centre muffler for the Holden VY/VZ 5.7L V8 one-tonne Crewman and ute — where its without-muffler sibling runs a bare pipe, this one chambers the centre to quieten the work ute.

What does the centre muffler change?

This dual centre assembly carries a muffler in the middle of the system, using internal chambers to settle the 5.7L V8 note before it reaches the rear. Compared with running the centre as a bare twin pipe, it takes the harshness out of the cabin — the calmer choice for a ute that's worked or driven long distances.

Why the work-ute routing?

The VY/VZ one-tonne Crewman and ute use a heavier-duty floor and chassis than the sedan, so this centre assembly is built for that body. The 2in dual layout and mounts are set to clear the one-tonner's underside and tailshaft rather than a passenger car.

Which models is it listed for?

It's listed to fit the Holden VY and VZ 5.7L V8 one-tonne Crewman and ute. Confirm your exact model and centre layout with the workshop before ordering, as the work-ute setup differs from the standard ute.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men supplies and fits the MPI Automotive SSMBM378MF in-house across the Illawarra. As a centre assembly we mock it on the hoist, confirm the twin 2in muffler clears the heavy-duty floor and tailshaft, and weld or clamp it in. Send your model and we'll confirm fit and book a bay.

Common questions

Is the SSMBM378MF quieter than the without-muffler version?
Yes — the chambered centre muffler settles the V8 note more than a bare centre pipe, making it the more subdued choice for this Crewman/ute.
Does it suit the one-tonne ute?
It's listed for the Holden VY/VZ 5.7L V8 one-tonne Crewman and ute. Confirm your exact model and centre layout with the workshop.
