Holden Commodore VF V8 Sedan Wagon 2.5in With Extractors Hotdog/Muffler.
Category: Extractors and headers


The MPI Automotive MKHN0328 is the 2.5in extractor-and-exhaust package for the Holden Commodore VF V8 sedan, built around a single hotdog muffler. The 2.5in sizing is the point of difference here: the tighter-bore street build that keeps gas speed up rather than chasing the biggest pipe.
At 2.5in this is the keener-bore option in MPI's VF extractor range. A 2.5in run holds exhaust velocity better than a larger pipe through the lower and middle rev range where a road-driven V8 spends most of its time, so it favours response and tractability over outright top-end flow. It pairs that with a hotdog muffler, a compact straight-through silencer that lifts the note over stock without the bulk of a full chambered box. For a daily-driven VF sedan, it's the restrained, drivable end of the range.
This is a header-back overhaul: it starts at the cylinder heads with tuned-length extractors that swap out the factory cast manifolds, then carries through to the matched 2.5in exhaust and its hotdog muffler. The cast manifolds and the original VF pipework both come out and are replaced as one MKHN0328 set, so the system flows as a designed whole rather than a part-pipe patch.
It's listed to fit the Holden Commodore VF V8 sedan. Because an extractor system is tied to a specific body and driveline, the exact build matters: send your VF details and the workshop confirms fitment, including how the 2.5in run clears the floor on your car, before anything is ordered.
Oak Flats Muffler Men supplies and fits MPI extractor packages like the MKHN0328 in-house across the Illawarra. Header work means pulling the factory manifolds, fitting the primaries, then hanging the 2.5in run and hotdog muffler and checking clearances under the floor. At an RRP of $4,759.17 it's a special-order set, so we confirm the fitment and lead time with you before booking the bay.
