The MPI Automotive MBM449MF is a 3in dual rear muffler assembly listed to fit the Holden Commodore sedan from VT to VZ. The dual rear layout is what sets it apart — it splits the flow into two paths at the back of the car rather than running a single muffler.

What does a dual rear muffler give you?

A dual rear runs two outlets at the tail, which spreads the gas across a pair of paths and gives the back of the car the twin-exit look and a fuller note than a single muffler. The MBM449MF is the rear assembly for that layout on the VT-VZ sedan, sitting at the very back of the system where it sets the cruise and idle character. It quietens by chambered absorption rather than by choking the flow.

Why the 3in bore?

At 3in this is built around a wider pipe diameter, which suits the larger or worked end of the Commodore range where a narrower bore would hold the system up at the rear. The bore is matched to the gas volume so the dual rear flows cleanly into both outlets.

Does it suit my VT-VZ Commodore?

It's listed for the Commodore sedan across the VT through VZ run. That's a broad span of model-year changes, so the exact rear floor and hanger layout can vary — send your build and we'll confirm the assembly suits before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the MBM449MF in-house. We confirm the VT-VZ build, set the dual rear onto its hangers, and align both outlets so they sit even and clear the rear bar. Book it in and we'll match it to your car.

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