The MPI Automotive SSMBM405PHD swaps the chambered centre can for dual centre hotdogs — compact straight-through resonators — on the VZ HSV sedan, at a 2in bore. The hotdog design is the point of difference: freer flow and drone control rather than maximum hush.

What are the dual centre hotdogs?

A hotdog is a small straight-through resonator, and the SSMBM405PHD is the centre pair for the VZ HSV sedan's twin-pipe system at a 2in bore. Mounted mid-run, they let gas pass down a perforated core to cut a resonant frequency without choking flow the way a fully chambered muffler can.

Hotdogs versus a chambered centre muffler

Pick hotdogs when you want freer flow through the centre and only the boomy drone reined in, rather than the broad hush of a packed muffler. On an HSV sedan that keeps more of the car's voice while taming the resonant frequencies. As straight-through devices they sit louder than a chambered can but tidier than open pipe.

Will they suit my VZ HSV?

They're listed to fit the VZ HSV sedan, as the dual centre pair. HSV built several VZ variants, so confirm your exact model, dual layout and existing bore with the workshop before ordering — a 2in centre section suits a matching run.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits centre hotdogs like these in-house across the Illawarra. We confirm the HSV twin-pipe setup, check hangers and floorpan clearance on both pipes, and splice them in on the hoist. Send your Holden's details and we'll book the bay.

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

Common questions

How do the SSMBM405PHD hotdogs differ from a centre muffler?
They're straight-through resonators, so they favour flow and drone control over the broad quietness of a chambered muffler, at a 2in bore.
Are they sold as a pair?
Yes — they're the dual centre pair for the VZ HSV sedan's twin-pipe system.
Will they fit a standard VZ Commodore?
This listing is HSV-specific. Confirm a standard Commodore fitment with the workshop first.
