The MPI Automotive MBM405MF is a dual centre muffler set for the VZ HSV sedan, built around a 2in bore. As a pair of chambered centre boxes, it does the bulk of the mid-system quietening on these Holden-based performance sedans — the dual chambered-muffler format is what defines it.

What do dual centre mufflers do?

These sit in the middle of the system as a twin set, one box per side, using internal chambers to absorb and reflect sound. That makes them the more thorough quietener of the mid-system options — they settle drone and mid-range note more than a straight-through resonator would. At 2in each, they're sized to the VZ-era system and shape the cruising tone heard inside the car more than the outright tailpipe volume.

Why the HSV VZ fitment?

This is listed for the VZ HSV sedan — the high-performance Holden-based variant — so the dual layout and 2in bore match that car's twin midsection. Running them as a pair lets each side breathe through its own centre box, keeping the system balanced left to right on these sedans.

Will it suit my VZ HSV, and how do we fit it?

It's listed to fit the VZ HSV sedan; confirm your exact model and build with the workshop before ordering. Oak Flats Muffler Men fits dual centre mufflers like these in-house in the Illawarra, checking both sides for hanger position, clearance and pipe alignment. MPI Automotive lists the MBM405MF at $720.48.

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