Twin 3in pipes the length of the car set the MPI Automotive SSMKHN0419 apart — a dual 3in extractor system listed to fit the Holden WH Statesman V8. With 1¾in primaries feeding both banks into separate 3in runs, it's built for the long-wheelbase Statesman, finishing through a hotdog resonator and muffler.

What does a dual 3in system mean here?

Dual means each cylinder bank gets its own 3in pipe rather than the banks collecting into a single run. On a long-wheelbase WH Statesman the dual layout suits the wider underbody, and it keeps the two banks separate from the extractors back. The 1¾in primaries feed each side, then the twin 3in runs carry a hotdog resonator and muffler.

Why 1¾in primaries on the Statesman V8?

The 1¾in primary size keeps exhaust-gas speed up, which favours the low-down and mid-range response a heavier long-wheelbase car uses most. The extractors swap the factory cast manifolds for mandrel-bent tube-and-merge runners. It's general engine theory — no flow or power numbers are published, and we won't quote any.

Will it suit my WH Statesman?

It's listed to fit the Holden WH Statesman V8. The long-wheelbase body and dual routing are the key checks, so confirm your exact car with us against the listing before ordering. Feed data is a starting point, not the final word.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits WH Statesman systems in the Illawarra. We check the 1¾in extractor flanges to your heads, route both 3in pipes the length of the car with proper clearance, and seal the joints for heat cycling. RRP is listed at 5362.76 AUD; fitting is quoted once we've seen the car.
