The MPI Automotive SSMKHN0271 runs full chambered mufflers rather than a resonator, making it the quieter, more subdued 2.5in dual cat-back for the VT–VZ Holden Commodore V8 wagon. It is the option for owners who want the flow gain without lifting the cabin volume much over stock.

What does the muffler configuration do here?

This version finishes through chambered mufflers, which quieten by reflecting and absorbing sound inside baffled chambers rather than passing it straight through. On the long wagon floor that keeps the note restrained at idle and cruise — a more conservative voice than a hotdog or open design, while the 2.5in pipework still relieves the factory restriction.

Why run it as a 2.5in dual system?

At 2.5in the bore suits a standard or mildly modified Commodore V8 — sized to flow without being oversized for a street car. Built dual, it carries two pipes from the cat-back back, which matches the wagon's rear floor layout and balances flow across both banks.

Is it listed to fit my wagon?

It is listed to fit the Holden Commodore V8 wagon over the VT–VZ generations. Because wagon rear sections differ from the sedan and ute, send your exact build to the workshop so we can confirm hangers and clearance before ordering.

What happens when we fit it in the Illawarra?

Oak Flats Muffler Men carries out the supply and fit at our Illawarra workshop, checking hanger alignment and rear-axle clearance on the bench before it goes on. The listed RRP is AUD 1,974.59. Drop in or send your details and we will confirm the build.

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

Common questions

How is the SSMKHN0271 different from the hotdog version?
This one uses full chambered mufflers for a quieter, more subdued note, where the hotdog sibling uses a straight-through resonator. We can talk through which character suits you.
Will it suit a daily-driven wagon?
Yes — the chambered muffler design keeps volume restrained, which suits a daily-driven VT–VZ V8 wagon. Confirm your build with the workshop first.
