Listed for the HSV-badged sedan, the MPI Automotive MKHN0402 is a 3in dual extractor system for the VY/VZ V8 HSV Sedan, running 1¾in primaries into a hotdog-and-muffler rear. It's the HSV sedan build in the VY/VZ extractor range rather than a standard Commodore or wagon fitment.

What makes this the HSV sedan build?

The MKHN0402 is listed specifically for the VY/VZ V8 HSV Sedan, so it's routed for that sedan body rather than a ute or wagon. HSV ran its own driveline and rear arrangement over the standard Commodore, and this system is specced to that sedan platform. It runs a 3in dual layout off 1¾in primary extractors and finishes through a hotdog resonator and rear muffler for a present but not raucous note.

Why 1¾in primaries and a hotdog rear?

Tubular extractors replace the cast manifolds at the heads; the 1¾in primary size keeps gas velocity up for street low- and mid-range on the V8. The hotdog-and-muffler combination lifts the note a touch over a twin-muffler build while keeping it civil in a sedan. The whole thing is a matched 3in engine-back package — headers, dual pipework, hotdog and muffler sized together. We have no published flow or sound figures, so the description is about the build, not a measured claim.

Will it suit my VY or VZ HSV Sedan?

It is listed to fit the VY/VZ V8 HSV Sedan. Confirm your exact HSV model, series and any prior exhaust changes with the workshop before ordering, since feed data on these can be imperfect.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits HSV and Commodore extractor systems in-house across the Illawarra. We confirm extractor access at the heads on the sedan, then route the 3in dual run, hotdog and rear muffler. At an RRP of $4,303.60 it's a build-to-order item; send your HSV details for fitment confirmation.
