The MPI Automotive SSMBM170PHD swaps the centre boxes on a VT-VZ V8 Commodore sedan for a pair of hotdogs — compact straight-through resonators — in a dual layout. Hotdogs flow more freely than chambered centre mufflers, which is why MPI recommends this set for manual cars.

What is a hotdog and why a pair?

A hotdog is a short straight-through resonator: a perforated core wrapped in packing, with no baffles to bend the flow. Run as the centre elements in a dual system on a V8 sedan, the pair keeps the exhaust freer-flowing than chambered centre mufflers and trims harsh frequencies rather than heavily muffling. The result is a louder, freer mid-system than the factory boxes.

Why is it recommended for manual cars?

MPI lists this hotdog set as the recommended choice for manual VT-VZ V8s. A manual driver tends to want the freer flow and harder note a straight-through resonator gives, where an auto owner more often prefers the quieter chambered centre muffler. That's a fitment recommendation from the supplier, not a hard rule — confirm your preference with the workshop.

Which Commodores does it fit?

It's listed to fit the Commodore sedan in V8 form across the VT, VU, VY and VZ series, in the dual centre position. Confirm your exact series and build with the workshop before ordering.

How do we fit it in the Illawarra?

Oak Flats Muffler Men fits dual hotdog sets in-house across the Illawarra, matching both resonators to the centre hangers on your V8 sedan. MPI Automotive lists it at $872.08; send your VT-VZ details through and we'll confirm the fit and the note you're after.

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

Common questions

Are these hotdogs louder than the factory centre mufflers?
Yes — a hotdog is a straight-through resonator, so the pair flows freer and gives a louder, harder note than chambered centre boxes.
Why does MPI recommend this set for manuals?
Manual drivers usually want the freer flow and firmer note hotdogs give; it's a supplier recommendation, not a rule. Confirm your preference with the workshop.
