Holden WK WL Statesman V8 3in Dual With 1 3/4 in Extractors Muffler/Muffler.
Category: Extractors and headers


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.
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.
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.
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.
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.
