The MPI Automotive SSMKHN0140 is a dual 2.5in cat-back with a hotdog resonator, listed to fit the VZ HSV V8 Sedan. The hotdog leads — a compact straight-through resonator on a dual layout that opens the rear of an HSV sedan's V8 without full mufflers.

What does the hotdog bring to a dual HSV system?

A hotdog is a short straight-through resonator — perforated core, absorptive packing, gas flowing straight through. On a dual 2.5in HSV sedan setup it gives a harder, freer note than a chambered muffler while staying compact across both banks. It's the more open of the dual builds, suited to an owner chasing more presence from the cat-back back.

Why dual 2.5in?

The system splits into two 2.5in banks, which suits the HSV sedan's twin-exit rear and keeps gas speed up on each side. Twin 2.5in carries V8 volume without stepping to a single larger pipe. We quote only the 2.5in diameter MPI lists for this part and make no combined-area claim.

Will it fit my VZ HSV?

The SSMKHN0140 is listed to fit the VZ HSV V8 Sedan across the Holden and HSV range. The sedan rear and dual routing are model-specific, so confirm your exact build and rear-end layout with the workshop before ordering to be sure the twin exits and hangers align.

What's fitting like at Oak Flats?

Oak Flats Muffler Men supplies and fits this MPI dual section in-house across the Illawarra. We check both banks' flanges, hangers and clearance against your HSV first. It's typically a special order — send your build and we'll confirm availability and timing.
