The MPI Automotive MKHN0301 is a 2.5in dual extractor package for the WK and WL Statesman V8, finished with a muffler and tailpipe. The twin 2.5in routing is the defining feature — two pipes back rather than a single run, sized for street response.

What does a 2.5in dual layout mean here?

Dual means two separate 2.5in pipes carried back from the extractors rather than one. On a long-wheelbase WK/WL Statesman V8 that's the symmetric, full-width back half, with each side keeping gas speed up at the 2.5in bore for low-down and mid-range response. The package finishes with a muffler and a tailpipe, so it's a complete extractors-back run for the car.

How does the Statesman wheelbase affect fitment?

The WK and WL Statesman sit on the long-wheelbase platform, so the exhaust has more length to route than a standard sedan and the hanger points differ. The MKHN0301 is listed for that body and the V8, with the dual routing set to suit it — confirm your exact Statesman build before ordering, as these have been modified over the years.

What do the extractors do, honestly?

Extractors replace the cast factory manifold with tubular headers, each cylinder running its own primary before they merge for a cleaner exit off the heads. The trade on a V8 Statesman is extra fitting time, more under-bonnet heat and tighter clearance than the original casting. The 2.5in dual pipework, muffler and tailpipe are supplied as one matched package.
