Holden Commodore VT - VZ V8 Sedan 3in Single With Extractors Muffler/Muffler.
Category: Extractors and headers


The MPI Automotive MKHN0122 is a 3in extractor-and-pipe system listed to fit the Holden Commodore VT–VZ V8 Sedan — tuned-length extractors off the heads through to twin mufflers, supplied as a complete kit rather than a single muffler swap.
This is the full extractor-back run for the Holden Commodore VT–VZ V8 Sedan: tuned-length extractors that bolt to the heads, then the connecting pipes and the rear section, which runs a muffler on each side. The pipework is listed at 3in. It is a single (rather than dual) sedan system.
Extractors (also called headers) replace the cast factory manifolds with tuned-length tubes — one primary per cylinder — that merge downstream, letting each cylinder breathe out with less back-pressure than the restrictive factory casting. That is the usual reason owners of these V8s fit them. The trade-off is real: they change the exhaust note and, depending on the merge and the factory emissions hardware, can affect how the car presents at inspection. Matching the 3in pipework to the rear keeps the result usable on the street.
It is listed to fit the Holden Commodore VT–VZ V8 Sedan; confirm the exact build before ordering. Feed data on parts like this can be imperfect, and the VT through VZ Commodore ran across several body styles and drivelines. This is the sedan fitment. Give us your build details and Oak Flats Muffler Men, here in the Illawarra, will match them against the listing before anything is ordered.
Extractors touch the part of the system the regulator looks at, so road legality depends on your specific car and how it presents at inspection in NSW — we cannot promise a blanket pass. The supplier does not publish a compliance approval for this listing and we will not claim one. Bring the car in and we will talk through what fitting extractors means for your registration before anything is cut or bolted up.
