The SSMBM449MF is a 3in dual rear muffler for the Holden Commodore VT–VZ sedan — the rear silencing for the twin-rear V-platform sedans, sized to a 3in system.

What does this VT-VZ rear cover?

This is the rear muffler section for a Commodore VT through VZ sedan running a dual 3in rear. It sits at the back of the system doing the final silencing before the tailpipes. The 3in bore keeps the rear flowing on a larger system rather than necking back to a stock outlet.

Which models is it listed for?

It's listed to fit the Holden Commodore VT, VX, VY and VZ sedan across the VT–VZ generation. These shared rear floor geometry, which is why one part spans the run. Confirm your exact model and rear layout with the workshop before ordering.

How does the dual 3in layout work?

The dual rear splits the flow to two tailpipes at the back of the sedan. Built to a 3in bore, the section keeps both sides flowing evenly to the tail rather than necking back to a single stock outlet. We check the inlet and outlets match your existing pipework before fitting, since the VT–VZ run covers a few rear variations.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men supplies and fits the MPI Automotive SSMBM449MF in-house across the Illawarra. We hoist the car, line the rear section up with the hangers and tailpipe exits, check it clears the rear floor, and confirm even sit before welding or clamping. Sourced through MPI Automotive, it's a tidy rear-section swap once the car is up. Send your model and we'll confirm fit and book a bay.
