The MPI Automotive MBM447MF is a 3in dual centre muffler set for the Holden Commodore sedan across VT to VZ. As a pair of chambered centre boxes, it's the more thorough mid-system quietener — the dual chambered-muffler format on the sedan body is what defines it.

What do dual centre mufflers do here?

Mounted mid-system as a twin set, these chambered boxes absorb and reflect sound internally, settling drone and the mid-range note more than a straight-through resonator would. At 3in each they keep the wider bore through the centre of a Commodore sedan system built for more flow, while doing the bulk of the cabin-side quietening. They influence cruising tone more than the outright volume at the tailpipe.

Why the sedan-specific fitment?

This dual set is listed for the Commodore sedan across VT to VZ, which routes its centre pipework differently to the wagon and ute. The sedan layout determines where the twin boxes sit and how they clear the floorpan, so matching the part to the body is what keeps the system balanced left to right.

Will it suit my VT-VZ sedan, and how do we fit it?

It's listed to fit the Commodore sedan across VT to VZ; confirm your exact model and build with the workshop, as the wagon and ute differ. Oak Flats Muffler Men fits dual centre mufflers like these in-house in the Illawarra, checking both sides for hangers, clearance and 3in pipe alignment. MPI Automotive lists the MBM447MF at $843.56.
