The MPI Automotive MKHN0130 is a 2.5in dual extractor-back exhaust listed to fit the VY and VZ HSV V8 sedan. It runs tuned extractors into a 2.5in dual system with a hotdog resonator and a muffler, the smaller-bore street build for these HSV sedans.

What does this MKHN0130 system cover?

This package starts at the cylinder heads with tubular extractors and runs a 2.5in dual system rearward through a hotdog resonator and a muffler. On the VY and VZ HSV sedan that's the complete exhaust path from the engine back. The 2.5in dual bore is the smaller pipework in this listing, and the hotdog-plus-muffler combination sits between a stripped line and a fully silenced build for noise.

What does a hotdog-and-muffler 2.5in dual setup change?

Extractors replace the cast factory manifolds with tubular runners that merge downstream, easing back-pressure off the heads and changing how the V8 breathes. The 2.5in dual layout carries two pipes rearward. A hotdog resonator paired with a muffler tames the note more than a resonator alone but stays louder than stock. The trade-off is plain: the smaller 2.5in bore keeps things tidy, and the resonator-and-muffler pairing lands a touch sharper than a twin-muffler build while staying street-civil.

Will it suit my VY or VZ HSV sedan?

It's listed to fit the VY and VZ HSV V8 sedan — both series across the one part, with the V8 driveline assumed. A wagon, ute or six-cylinder Commodore will need a different listing. Treat the fit as listed to fit, not guaranteed, and confirm your exact HSV series and build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits extractor systems like this in-house across the Illawarra. We confirm the VY or VZ HSV sedan fitment, check extractor clearances and align the 2.5in dual routing, the hotdog and the muffler before booking the bay. As an MPI Automotive system it can be special-ordered in if it's not on the shelf.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

Will the MKHN0130 fit my VY or VZ HSV sedan?
It's listed to fit the VY and VZ HSV V8 sedan. Confirm your exact series with the workshop before ordering.
What's the hotdog for?
The hotdog is a resonator in the 2.5in dual line; paired with the muffler it silences the note while staying louder than stock.
How does it differ from the twin-muffler version?
This pairs a hotdog with one muffler and runs a touch sharper; the twin-muffler build is quieter.
