Holden Commodore VT - VZ Wagon - Ute 3in Dual Centre Hotdog Assembly for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive MBM446PHD is a 3in dual centre hotdog assembly for the Holden Commodore wagon and ute across VT to VZ. Built as a twin set of straight-through resonators, the hotdog format is its defining feature — free-flowing tuning bodies that cut drone rather than silencing through chambers.
A hotdog is a compact straight-through resonator: gas passes straight through a slim body, targeting drone and resonance while flowing freely, unlike a chambered muffler that quietens more aggressively. Supplied as a 3in dual centre assembly, this set runs two resonators through the middle of the system, one per side, keeping the midsection breathing on the larger-bore Commodore. As a centre piece it shapes cruising tone more than tailpipe volume, and leans freer-flowing than a centre muffler.
This assembly is listed for the Commodore wagon and ute bodies across VT to VZ, which route their centre pipework differently to the sedan. The 3in bore matches a wider system, and supplying it as a complete dual assembly keeps both sides balanced. The wagon/ute distinction is the detail to confirm against your exact body.
It's listed to fit the Commodore wagon and ute across VT to VZ; confirm your exact body and build with the workshop, as the sedan routes differently. Oak Flats Muffler Men fits centre hotdog assemblies like this in-house in the Illawarra, checking both sides for hangers, clearance and 3in pipe alignment. MPI Automotive lists the MBM446PHD at $786.52.
