Holden Commodore VP VR VS Sedan 5L V8 Auto IRS 2.5in With Extractors Muffler (SKU: MKHN0392SC) Engineered
Category: Extractors and headers


The MPI Automotive MKHN0392SC is a 2.5in extractor-based system listed to fit the Holden Commodore VP, VR and VS sedan with the 5L V8, automatic and IRS. It pairs extractors with a muffler for a complete header-back package.
This is an extractor kit run through to a muffler at 2.5in, so it replaces the factory manifolds and the pipework behind them in one package for the V8 Commodore sedan. The extractors are the headers off the heads; the 2.5in pipe and muffler carry the gas back and set the note. It is specified for the auto, independent-rear-suspension VP, VR and VS, which is why the routing suits that body and driveline.
Extractors replace the cast manifolds with tuned tubular runners, the idea being to scavenge spent gas more evenly from each cylinder than a one-size casting. Going to a 2.5in system behind them opens the pipe over stock. The trade-off is honest: tubular extractors can be more prone to heat soak under the bonnet, and a larger pipe with a freer muffler is louder than the factory item. How much louder depends on the muffler, which we have not measured.
It is listed to fit the 5L V8 VP, VR and VS sedan with automatic and IRS. The auto and IRS callouts matter, since manual cars and live-axle variants can route differently. Confirm your exact build with the workshop before ordering.
Whether an extractor-back system suits a registered car depends on your state emissions and noise rules; confirm requirements with the workshop. Oak Flats Muffler Men fits systems like this in-house across the Illawarra, checking flange fit, clearance over the IRS and that the muffler hangs cleanly before the car goes back on the road.
