The MPI Automotive SSMKHN0399 is a 3in dual extractor package with 1-3/4in extractors and twin mufflers, listed to fit the Holden Commodore VT to VZ V8 sedan. It's a full front-to-rear change rather than a tailpipe-only swap.

What does this package cover?

This is a dual extractor-back build for the VT–VZ sedan: 1-3/4in extractors off the V8, 3in dual pipework rearward and twin mufflers at the back. It's the whole system from the heads back, carrying a complete-job RRP of $5,425.38. 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 and the twin mufflers settle the tone. It's louder than stock; how much depends on your build.

Will it suit my VT to VZ Commodore V8 sedan?

It's listed to fit the Holden Commodore VT to VZ V8 sedan. MPI lists the series range 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-back systems like this in-house across the Illawarra. We fit the 1-3/4in extractors to the heads, route the 3in dual pipework, hang twin mufflers 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.
