The MPI Automotive MKHN0136 is a 3in dual extractor-back exhaust listed to fit the VY and VZ V8 HSV sedan. It runs 1-7/8in tubular extractors into a 3in dual system with a hotdog resonator and a muffler, the larger-bore street build for these HSV sedans.

What does this MKHN0136 system cover?

This package starts at the cylinder heads with 1-7/8in tubular extractors and runs a 3in 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 3in dual bore is the larger pipework on offer here, and the hotdog-plus-muffler combination sits between a stripped line and a fully silenced build for noise.

What does a 1-7/8in extractor and 3in 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 1-7/8in primary size sets the runner diameter, and the 3in 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: more pipe and tubular runners over the cast manifolds, with the resonator-and-muffler pairing keeping it street-civil.

Will it suit my VY or VZ HSV sedan?

It's listed to fit the VY and VZ V8 HSV in sedan body — 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 the 1-7/8in extractor clearances and align the 3in 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 MKHN0136 fit my VY or VZ HSV sedan?
It's listed to fit the VY and VZ V8 HSV sedan. Confirm your exact series with the workshop before ordering.
What size are the extractors and pipework?
The extractors are 1-7/8in and the system behind them is 3in dual, the larger pipework in this listing.
Is it loud?
It runs a hotdog resonator and a muffler, so it's louder than stock but more silenced than a system without the muffler.
