Built as the rear muffler for the long-wheelbase Holden Grange, the MPI Automotive SSMBM459MF is the chambered tail-end silencer that sets the cabin note on these V8 limousines. It's a 2in muffler, so it suits the stock-to-mild end of the range rather than a heavily worked engine.
Where does a rear muffler sit in the system?
The rear muffler is the last silencing stage before the tailpipe, so it does the most to shape what you actually hear at the kerb and inside the cabin. A chambered muffler like this quietens by reflecting and absorbing pulses through internal baffles, which keeps a V8 civil at idle and on the highway while still letting it breathe. On a stretched body like the Grange, the rear muffler also has to clear the longer floorpan and rear suspension, so packaging matters as much as flow.
Which engine size does the 2in bore suit?
At 2in this muffler is matched to a stock or lightly modified V8 rather than a big-bore build chasing maximum flow. That keeps gas speed sensible through the silencer and the note measured. MPI Automotive lists it to fit Holden and HSV applications; the larger 6.0L cars are exactly the kind of grand tourer this part is meant to keep quiet and composed.
Will the SSMBM459MF suit my car?
It's listed to fit the Holden WK/WL Grange V8 and its HSV equivalents. Because these are low-volume long-wheelbase cars, the exact bracketry and hanger positions vary — send your build to the workshop and we'll confirm it lines up before ordering.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this rear muffler in-house across the Illawarra. We check the hanger geometry, the clearance to the floor and tank, and the alignment to the existing pipework before we sign it off.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What does the SSMBM459MF actually change?
- It replaces the rear muffler only, so it sets the final tailpipe note and the cabin sound rather than altering the whole system.
- Is this a loud muffler?
- It's a chambered rear muffler at 2in, which is the quieter, more measured design — it keeps a V8 composed rather than raucous. We can't quote a decibel figure.
- Will it fit my HSV Grange?
- It's listed to fit Holden and HSV Grange V8 applications. Confirm your exact WK or WL build with the workshop first.
