How is this quieter than the hotdog version?

It uses two mufflers in the 3in dual run rather than a hotdog resonator and one muffler, so it leans toward a more subdued note.

Are the extractors a larger bore?

Yes — 1-7/8in primaries, which suit a higher-rpm WH Statesman V8 build.

Can you supply and fit it?

Yes, Oak Flats Muffler Men does both in-house across the Illawarra after confirming your build.

The MPI Automotive SSMKHN0295 runs a twin-muffler 3in dual layout behind 1-7/8in extractors for the Holden WH Statesman V8. Two mufflers in the run is the distinguishing choice — it leans the quietest of the WH big-bore options for owners who want the cruise kept civil.

Why two mufflers?

This SSMKHN0295 carries a muffler in each side of the 3in dual run rather than a resonator-plus-muffler split. More silencing volume means a more subdued note for a long-wheelbase Statesman that spends its time touring — the V8 character is there, but the cabin stays liveable on a highway run.

What do the 1-7/8in primaries change?

At the head, 1-7/8in tube extractors replace the restrictive cast manifolds. The larger primary bore suits a WH Statesman V8 built to rev, opening flow up top in exchange for a touch of low-rpm gas speed. It's an application call rather than a blanket gain.

Is the 3in dual road-suited?

A 3in dual pipe matches the bigger primaries so the system isn't pinched behind the head. With twin mufflers it's biased toward a quieter on-road result, which suits the Statesman's role as a comfortable long-distance car.

How does the workshop handle fitment?

Oak Flats Muffler Men in the Illawarra supplies and fits this head-back package in-house. It's listed to fit the WH Statesman V8; confirm your exact build with us so we can check clearances and hangers before booking.

How is it ordered and supplied?

The SSMKHN0295 is an application-specific MPI Automotive part we bring in against your confirmed WH Statesman, not a generic system off the rack. If a quieter cruise is the priority, the twin-muffler layout is the reason to pick this listing over the resonator-based one; we confirm that fits the brief before ordering.
