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


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.
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.
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.
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.
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.
