The MPI Automotive MBM405PHD is a dual set of centre hotdogs — compact straight-through resonators — for the VZ HSV sedan, built around a 2in bore. The hotdog format is the point of difference: slim, free-flowing tuning bodies that cut drone without the volume drop of a chambered muffler.

What is a hotdog and how does it differ from a muffler?

A hotdog is a compact straight-through resonator — gas passes straight through a slim cylindrical body rather than weaving through internal chambers. That makes it a tuning device that targets drone and resonance while flowing freely, so it stays louder and freer than a chambered centre muffler. As a dual centre set on the VZ HSV, the pair sits mid-system and shapes the note without heavily silencing it.

Who suits the dual centre hotdog set?

These suit a VZ HSV owner who wants the mid-section to flow freely and keep more of the V8 character, accepting more volume than a chambered centre box would allow. Run as a 2in dual set, one per side, they keep the twin midsection balanced while leaning to the freer-flowing end of the centre options.

Will it suit my VZ HSV, and how do we fit it?

It's listed to fit the VZ HSV sedan; confirm your exact model and build with the workshop first. Oak Flats Muffler Men fits centre hotdog resonators like these in-house in the Illawarra, checking both sides for hangers, clearance and pipe alignment. MPI Automotive lists the MBM405PHD at $618.42.

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

Common questions

Will the hotdogs be louder than centre mufflers?
Yes — hotdogs are straight-through resonators that flow more freely and quieten less than chambered centre mufflers, so they lean louder.
How many are in the MBM405PHD?
It's a dual set — two 2in centre hotdog resonators, one per side, for the VZ HSV sedan.
