Sized at 3in with 1¾in primary tubing, the MPI Automotive MKHN0414 is a tubular extractor-and-exhaust package listed to fit the Holden WH Statesman V8. The 1¾in primaries keep gas speed up for low- and mid-range response on a street V8, and the rear runs a muffler-and-muffler arrangement for a settled note in a long-wheelbase car.
Why 1¾in primaries on the WH Statesman?
The 1¾in primary tube is the defining choice here. On a street-driven V8 like the WH Statesman's, primaries of this size hold exhaust velocity through the runners, which helps off-idle and mid-range pull rather than chasing peak high-rpm flow. They merge into a 3in run, so the system is bored for the engine without going larger than the application wants. This is the muffler-and-muffler build in the WH range, meaning two mufflers handle silencing — the quieter, more touring-oriented option for a big Statesman body.
What does a tubular extractor change?
Extractors replace the factory cast manifolds with equal-length-style tubular runners off each port, easing the path gas takes to merge and reducing restriction at the heads. On the MKHN0414 those 1¾in runners feed a complete 3in engine-back system, so you are buying a matched package rather than headers alone. We have no published flow or sound figures to quote, so the honest case for it is the consistent, purpose-sized tube-and-merge design over a cast manifold.
Will it suit my WH Statesman?
It is listed to fit the Holden WH Statesman V8. The WH is the long-wheelbase luxury Commodore platform, and this build is specced around that body's routing. Confirm your exact WH specification and any prior driveline changes with the workshop before ordering, as feed data can be imperfect.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Statesman extractor systems in-house across the Illawarra. We check extractor clearance at the heads on the WH, then route the 3in run and both mufflers under the long body. At an RRP of $4,504.73 this is a build-to-order package; send your WH details and we'll confirm the fitment before booking the bay.
