A 3in dual run for the long-wheelbase Statesman, the MPI Automotive SSMKHN0421 pairs 1¾in extractors with a hotdog muffler, listed to fit the Holden WK and WL Statesman V8. It's listed at $5,472.20.

What does the 3in dual layout mean here?

The SSMKHN0421 runs a 3in dual system — twin pipes for the V8 — under the WK/WL Statesman. The Statesman is the long-wheelbase Holden, so a dual layout suits the longer body and the V8's two banks, giving each side its own pipe. The defining points of this version are that dual 3in routing and the hotdog finish, built for the WK and WL.

Why a hotdog muffler on the Statesman?

This version uses a hotdog muffler — a straight-through resonator-style silencer rather than a chambered box. On a long-wheelbase luxury Holden it keeps the note more open than a twin-muffler layout while still doing the silencing job. It's the leaner-silencing finish on the dual 3in system for owners who want a bit more voice.

What do the 1¾in extractors bring?

The extractors use 1¾in primary tubing — the smaller-primary choice, which keeps gas speed up off the head and favours low-down and mid-range response. On a heavy long-wheelbase car that pull lower in the range is exactly what's useful. The extractors replace the factory cast manifolds with tube-and-merge runners.

Is it road legal, and how do we fit it?

As an extractor change this alters the exhaust at the head, so road compliance depends on the full build and your state's rules — we'll confirm that with you, not assume it. Oak Flats Muffler Men fits Statesman systems like this across the Illawarra; it's listed to fit the WK and WL Statesman V8, so send your build and we'll confirm clearances and the dual routing before booking the bay.
