The MPI Automotive MBM446MF is a 3in dual centre muffler for the Holden Commodore VT to VZ wagon and ute — a larger dual-bore mid-system silencer matched to the longer wagon and ute bodies rather than the sedan.

Why a wagon-and-ute-specific centre muffler?

Body shape drives this part: the VT–VZ wagon and ute have a different floor and rear length to the sedan, so the centre section routes differently. The MBM446MF is the 3in dual centre muffler built for those bodies, in the larger dual layout that suits a worked Commodore. Fitting the body-correct part means the silencer and pipes sit where the wagon or ute floor actually allows, not where a sedan part would want to go.

What does the 3in dual layout do?

At 3in in a dual arrangement, this centre muffler is sized for more output than a single small-bore V6 system. The chambers reflect and absorb pulses to control the note through the middle of the run while the dual bores keep the gas flowing. It's the mid-system silencer for a Commodore wagon or ute running a bigger exhaust than stock.

Will it suit my Commodore?

It's listed to fit the Holden Commodore VT to VZ wagon and ute as the 3in dual centre muffler. Confirm your body style and exhaust layout with the workshop, since the sedan takes different parts and the dual-3in sizing is for a larger system.

How is it fitted in the Illawarra?

Oak Flats Muffler Men fits these in our Illawarra bay. We position the dual centre muffler under the wagon or ute floor, check clearance and hangers along the longer body, and clamp or weld it in. Bring the car in and we'll confirm the part and book the work.
