The MPI Automotive MKHN0125 is a 2.5in dual extractor and exhaust package listed to fit the V8 Holden Commodore sedan from VT to VZ, running a hotdog resonator and a rear muffler.

What's the hotdog-and-muffler layout?

This 2.5in dual package uses a hotdog — a small straight-through resonator — ahead of the rear muffler, with tubular extractors feeding the system from the heads. The hotdog takes the edge off resonance in the mid-range while the rear muffler does the main silencing, which is a different balance from the twin-muffler version MPI also lists for this car.

What does an extractor system do?

Extractors replace the factory cast manifolds with tubular primaries so each cylinder vents through its own pipe before merging. The honest trade-offs are extra fitting time, lower ground clearance and more under-bonnet heat than stock manifolds. Because the result depends on the pipework behind the headers, this is supplied as a complete 2.5in dual run with the hotdog and muffler matched to the extractors.

Will it suit my VT–VZ V8?

It's listed to fit the V8 sedan across the VT to VZ generations. That's a wide platform window, so check your exact model year, engine and rear arrangement with the workshop before ordering rather than relying on the family listing alone.

What does fitting involve at our workshop?

Oak Flats Muffler Men supplies and fits this system in the Illawarra. We confirm the hotdog and muffler positions clear your floor and rear, verify the listed fitment against your build, and book the bay from there.
