The MPI Automotive SSMKHN0402 is a 3in dual extractor package with 1-3/4in extractors, a hotdog and a rear muffler, listed to fit the HSV VY and VZ V8 sedan. It changes the system from the heads back.

What does this package cover?

This build runs 1-3/4in extractors off the V8 into 3in dual pipework, with a hotdog resonator and a rear muffler for the VY/VZ HSV sedan. It's the whole run from the manifolds back, carrying a complete-job RRP of $5,277.39. MPI Automotive doesn't publish the pipe material or wall thickness here, so we confirm those details at the workshop.

What are extractors and what do they change?

Extractors, or headers, replace the cast manifolds with tubular primaries — 1-3/4in here so each cylinder gets a cleaner path to merge. On a V8 the aim is smoother flow off the heads and a fuller note than the factory manifolds give. The 3in dual pipework carries that flow; the hotdog trims drone and the rear muffler sets the tone. It's louder than stock; how much depends on your build.

Will it suit my VY or VZ HSV V8 sedan?

It's listed to fit the HSV VY and VZ V8 sedan. MPI lists the series, make and body type but not the model years here, so send your exact build — the workshop checks the manifold flanges, crossmember clearance and rear hangers before ordering. Listed to fit means we verify it against your car, not that it drops on unseen.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits dual extractor systems like this in-house across the Illawarra. We fit the 1-3/4in extractors to the heads, route the 3in dual pipework, hang the hotdog and rear muffler, and check clearances through the underbody. At this RRP it's typically a special-order item, so we confirm availability and your fitment before committing the order.

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