A hotdog resonator does the talking on the MPI Automotive SSMKHN0272 — a 2.5in dual cat-back built for the VT–VZ Holden Commodore V8 wagon. The compact straight-through hotdog trims drone without choking flow, so the wagon keeps a civil note under load.

What does the hotdog resonator change?

A hotdog is a short straight-through resonator: gas passes through a perforated core rather than around chambers, so it tunes out the worst of the cruising drone while shedding less flow than a full chambered muffler. On this 2.5in dual cat-back it sits inline on the wagon's long underfloor run, smoothing the note that a big body cavity tends to amplify on a Commodore V8.

Why a 2.5in bore on this wagon?

The 2.5in pipe size is matched to a stock or lightly worked V8 — enough section to let the engine breathe past the factory restriction without going oversized for a street car. Run as a dual system, it splits the gas across two pipes from the cat-back rearward, which suits the wagon's wider rear floor and keeps each bank flowing evenly.

Will it suit my VT–VZ Commodore wagon?

It is listed to fit the Holden Commodore V8 wagon across the VT to VZ range. Wagon floors and rear hangers differ from the sedan and ute, so confirm your exact build and body with the workshop before ordering — feed data is a guide, not a guarantee of fit.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this system in-house across the Illawarra. We check hanger positions, tailpipe exit and clearance over the rear axle before signing off, and the listed RRP is AUD 1,722.42. Send your VIN or build details and we will book the bay.

Common questions

What is the hotdog on the SSMKHN0272?
It is a compact straight-through resonator that reduces cabin drone with less flow loss than a full chambered muffler — a quieter cruise without a heavy muffler.
Does this fit a Commodore sedan?
No — the SSMKHN0272 is listed for the VT–VZ V8 wagon body. The sedan and ute use different rear routing. Confirm your body with the workshop.
