Running twin chambered mufflers on a dual 2.5in cat-back, the MPI Automotive SSMKHN0139 is listed to fit the VZ HSV V8 Sedan. The muffler-on-each-bank build is the angle — the most settled-sounding of the dual HSV sedan options.

Why a muffler on each bank?

The SSMKHN0139 carries a chambered muffler on both of its 2.5in banks, giving sound control across both exits. Chambered mufflers reflect and absorb pressure pulses through internal baffles, so the HSV V8 note stays measured at idle and on the highway. It's the choice when you want the dual-exit flow and look with a calmer tail than a straight-through resonator.

What does dual 2.5in suit on an HSV sedan?

Two 2.5in banks suit the sedan's twin-exit rear and keep gas speed up on each side, a balanced flow path for a V8 that isn't reaching for the single largest pipe. We state only the 2.5in diameter MPI lists for this part — no combined-area figure is published and none is implied.

Does it fit my VZ HSV Sedan?

The SSMKHN0139 is listed to fit the VZ HSV V8 Sedan across the Holden and HSV range. The rear routing is model-specific, so confirm your exact build and rear-end layout with the workshop before ordering so both banks, hangers and exits line up.

Fitting at our Illawarra workshop

Oak Flats Muffler Men supplies and fits this MPI dual section in-house. We measure both banks' flanges, hangers and clearance against your HSV before booking the bay. It's commonly a special order at this price — send your build and we'll confirm stock and lead time.

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

Common questions

How does the SSMKHN0139 differ from the hotdog version?
It runs a chambered muffler on each bank rather than a hotdog, making it the more subdued dual HSV sedan build. We describe sound by type only.
Is it a dual system?
Yes — dual 2.5in cat-back with twin mufflers, listed to fit the VZ HSV V8 Sedan. Confirm your build with the workshop.
Will it drone at cruise?
It uses chambered mufflers, the more subdued design. We have no decibel data and describe it by type only.
