Holden Commodore VT - VZ V8 Wagon 2.5in Dual Catback Hotdog/Muffler.
Category: Mufflers and resonators


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.
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.
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.
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.
