The MPI Automotive SSMBM449MF-HARROP is a 3in dual rear muffler for the Holden Commodore VT–VZ sedan. As a rear-muffler section it's the part that sets the car's final volume, built in 3in to suit a worked Commodore.
What does the dual rear muffler do on a VT–VZ?
The rear mufflers are the last quietening stage before the tailpipes. A chambered, absorptive muffler softens overall volume and rounds off the harshness, so on a Commodore sedan this is what decides how loud the car finishes at the back. Run as a dual layout in 3in, the SSMBM449MF-HARROP carries both sides through matched rear cans. It's the rear section specifically — it works with whatever centre and front pipework the car already has, so it's the targeted change for owners who want to alter the final note without redoing the whole system.
Why the 3in bore across the VT to VZ range?
At 3in this rear muffler is sized for a worked V8 Commodore rather than a stock small bore — it suits a car making more than standard and wanting the flow to match. It's listed to fit the Holden Commodore VT through VZ sedan, which spans several years of the platform, so confirm your exact model and rear hanger arrangement with the workshop before ordering to make sure the outlets and mounts line up on your car.
Is it road legal?
This is a rear-muffler section. It doesn't include or delete the catalytic converter, so the cat-delete off-road rules don't apply to this part. A rear-muffler change does alter how loud the car finishes, so confirm the in-service note and any state requirements with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits Commodore rear-muffler sets in-house across the Illawarra, hanging the dual rears, checking the tailpipe alignment and confirming the section suits your VT–VZ. The SSMBM449MF-HARROP carries a published RRP of $1,124.24; send your build and we'll confirm fitment and book the bay.
