Sized at 2in, the MPI Automotive MBM493MF is a rear muffler set built for the long-wheelbase Grange rather than a worked, big-bore build. It's listed to fit the Holden WM HSV Grange V8 6.0L, replacing the rear silencing on this luxury-length sedan.

What does the 2in bore suit on a Grange?

Bore leads the story here. At 2in this is the tighter rear-box size, which keeps exhaust velocity up and the cabin refined — the right read for a long-wheelbase Grange where composure matters more than chasing maximum flow. It's the measured choice for a 6.0L running close to its factory breathing in a luxury sedan.

How does a chambered rear muffler behave?

A chambered muffler quietens by reflecting and absorbing pulses inside the box, so it controls volume rather than freeing it. On the WM Grange the MBM493MF keeps the V8 present but subdued at the rear — a step from the factory boxes without the harder note a straight-through hotdog would bring to a car built for quiet.

Will it suit my WM Grange?

It's listed to fit the Holden WM HSV Grange V8 6.0L as a 2in rear muffler fitment. The Grange's long-wheelbase platform routes its tail differently to the short cars, so confirm your exact build with the workshop before ordering — feed data can be imperfect.
