The MPI Automotive MBM459MF is a 2in rear muffler listed to fit the Holden WK-WL HSV Grange 6.0L. As the last silencing box in the system, it shapes the note the long-wheelbase Grange leaves behind it.

Where does a rear muffler sit in the system?

The rear muffler is the final chambered box before the tailpipe, and on the WK-WL Grange it carries most of the silencing you hear from outside the car. The MBM459MF replaces only that rear box — the pipework and any centre silencing ahead of it stay as they are. As a chambered muffler it quietens by absorption and reflection rather than running straight through, so it favours a controlled, settled note over volume on a luxury long-wheelbase sedan.

What suits the 6.0L Grange?

This is a back-of-system part for the Holden-built, HSV-badged Grange with the 6.0L V8. Swapping the rear box is the least invasive way to alter the note without touching the rest of the run, which suits owners who want a tidy refresh of the rear silencing rather than a full system change. Listed by MPI Automotive at $900.60.

Will it suit my WK-WL HSV Grange?

It is listed to fit the Holden WK-WL HSV Grange 6.0L as a rear muffler. Feed data can be imperfect, so confirm your exact build with the workshop before you order rather than relying on the listing alone.
