The quietest dual build for the Statesman, the MPI Automotive SSMKHN0420 runs muffler-to-muffler on a 3in dual system with 1¾in extractors, listed to fit the Holden WK and WL Statesman V8. It's listed at $5,546.41.

Why muffler-to-muffler suits the Statesman

The SSMKHN0420 is defined by its muffler-to-muffler layout — two muffler stages on the dual 3in run rather than a single resonator. On the WK/WL Statesman, a long-wheelbase luxury Holden, that extra silencing keeps the cabin civil and the note restrained, which fits the car's character. It's the more-silenced choice of the dual builds.

What the 3in dual routing does

This is a 3in dual system — twin pipes, a bank each side for the V8 — routed under the longer Statesman body. The dual layout gives each bank its own path and the bigger pipe opens up the exhaust, while the two mufflers keep the result quiet. It's matched to the WK and WL Statesman.

What do the 1¾in extractors suit?

The extractors use 1¾in primary tubing — the smaller-primary option, which keeps gas speed up off the head and favours low-down and mid-range response. On a heavy long-wheelbase car, low and mid-range pull is the useful end of the range. The extractors replace the factory cast manifolds with tube-and-merge runners as the basis of the build.

Road compliance and fitting at our Illawarra workshop

Because it changes the exhaust at the head, road compliance depends on the full build and your state's requirements — we'll confirm that with you rather than have you assume it. Oak Flats Muffler Men fits Statesman systems like this across the Illawarra; tell us your exact build and we'll confirm clearances and the dual routing before booking the bay.
