The MPI Automotive MKHN0295 takes the WH Statesman V8 3in dual system and silences it with two mufflers — one per side, no resonator. That twin-muffler layout is its signature: a symmetric, balanced back half on 1⅞in primaries.

What does the twin-muffler layout give the Statesman?

Rather than a hotdog-and-muffler pairing, the MKHN0295 runs two mufflers across the 3in dual back half. On a long-wheelbase WH Statesman that means a muffler in each pipe, a balanced and restrained way to quieten a big V8 system. It's the choice for an owner who wants the dual presence kept civil through matched silencers.

Why 1⅞in primaries into a 3in dual?

The 1⅞in primaries are the larger of the common extractor sizes, suiting a higher-output V8 with flow up top. They feed a 3in dual run — two pipes carried the length of the long-wheelbase body — making this the big-bore Statesman package, with the silencing handled by the twin mufflers behind it.

Extractors on a V8 Statesman — the honest picture

Extractors replace the cast factory manifold with tubular headers, each cylinder running its own primary before they merge for a freer exit. The trade is extra fitting time, more under-bonnet heat and tighter clearance than the original casting. MPI supplies the 1⅞in primaries, 3in dual pipework and both mufflers as one matched package.
