The MPI Automotive SSMBM405MF is a 2in dual centre muffler for the VZ HSV sedan — the mid-system silencer in the twin-pipe exhaust on Holden's hotted-up VZ. The HSV-specific dual fitment is what marks it out from a garden-variety Commodore section.

What does the dual centre muffler do?

On the VZ HSV sedan's twin-pipe system, the SSMBM405MF is the centre silencer at a 2in bore. The gas splits into two pipes, and this section sits mid-run, absorbing and reflecting sound before the rear so it shapes the cruise note more than the tailpipe bark. It's listed for the HSV sedan rather than the standard Commodore.

Why the HSV-specific section?

HSV models ran their own exhaust routing over the VZ Holden, so the dual centre muffler is matched to that car. Naming HSV keeps the fitment honest — this is the performance sedan's part, sized at 2in per pipe to keep gas speed up through each side of the dual run.

Will it suit my VZ HSV?

It's listed to fit the VZ HSV sedan. HSV built several variants on the VZ Commodore, so confirm your exact model, dual layout and existing pipe size with the workshop before ordering — a 2in centre section belongs on a matching system.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits dual centre mufflers like this in-house across the Illawarra. We confirm the HSV twin-pipe setup, check hangers and clearances on both sides, and mate it on the hoist. Send your Holden's details and we'll book it in.
