The SSMBM378WOM is a 2in dual centre assembly without a muffler for the Holden VY/VZ 5.7L V8 one-tonne ute and Crewman — a straight twin centre pipe for the work-ute floorpan, with no silencing element in the middle.

What does the without-muffler centre give you?

This is the dual centre section run without a silencer in it — a straight twin-pipe through the middle of the system. With no centre muffler it leaves all the silencing to the rest of the system, so the 5.7L V8 note comes through more open. It's the freest-flowing centre choice for the one-tonne ute and Crewman.

Why the ute/Crewman-specific routing?

The VY/VZ one-tonne ute and Crewman ran a heavier-duty floor and chassis than the sedan, so the centre assembly is routed for that work-ute body. The 2in dual layout and mounting points are built to clear the one-tonner's underside 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 ute and Crewman. 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 at Oak Flats?

Oak Flats Muffler Men supplies and fits the MPI Automotive SSMBM378WOM in-house across the Illawarra. As a centre assembly we mock it on the hoist, confirm the twin 2in pipes clear the heavy-duty floor and tailshaft, and weld or clamp it in. Send your model and we'll confirm fit.

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