The MPI Automotive SSMBM493MF is a 2in rear muffler set for the WM Grange V8 — tail-end silencers for the long-wheelbase HSV limousine, sized to keep a 6.0L composed rather than loud. The Grange-specific fitment and the quieter 2in bore define it.

What does a rear muffler set do on the Grange?

The rear mufflers are the last silencing stage before the tailpipes, so they do the most to set what you hear at the kerb and in the cabin. On a long-wheelbase Grange — a car built to glide quietly — that final stage matters to the whole character of the drive. Chambered mufflers like these quieten by absorbing and reflecting pulses, keeping the V8 measured.

Why the 2in bore?

At 2in these rear mufflers are matched to a stock or lightly modified 6.0L rather than a big-bore build chasing flow. That suits the Grange's grand-tourer brief, keeping the note restrained and the gas speed sensible. MPI Automotive lists the set for the Holden WM Grange V8 in its HSV form.

Will it suit my WM Grange?

It's listed to fit the Holden WM Grange V8 (HSV). Because it's a low-volume long-wheelbase car, confirm your exact build and that the rest of your system matches with the workshop before ordering.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men supplies and fits these rear mufflers in-house across the Illawarra. On a stretched body we check the hanger geometry, the clearance to the floor and tank, and that the tips sit even before we sign it off.

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