Holden Commodore VN VP VQ VR VS V8 Sedan 3in Centre Muffler for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive SSMBM462MF is the centre muffler for the VN-VS Commodore V8 sedan — the mid-system silencer that does the heavy lifting on drone before the gas reaches the back of the car. It's a 3in unit, sized for a worked or free-breathing V8 rather than a stock setup.
A centre muffler sits in the middle of the system, ahead of the rear silencer, and is where a lot of low-frequency drone gets knocked down before it can resonate through the floorpan. On the older VN-VS Commodore sedan, getting this section right is the difference between a V8 that's pleasant on a long drive and one that booms at cruise. It quietens by absorption and reflection through its chambers while keeping the 3in path open.
At 3in this centre muffler is built for a V8 that's been opened up — a bigger-bore system that wants flow rather than the restriction of a stock pipe. Larger bore suits a modified or free-flowing engine; it's the wrong call for a stock daily that needs nothing more than the factory size. MPI Automotive lists it specifically for the sedan body, which routes differently from the ute and wagon under the floor.
It's listed to fit the Holden Commodore VN, VP, VQ, VR and VS V8 sedan. These cars have detail differences across the series, so confirm your exact model and the rest of your 3in system with the workshop before ordering.
