The MPI Automotive SSMKHN0418 takes the dual 3in WH Statesman layout and runs it quieter — twin 3in pipes the length of the long-wheelbase car, but with muffler-to-muffler silencing rather than a hotdog. Its 1¾in primaries keep the street-engine character on the Holden WH Statesman V8.

Why twin mufflers on a dual 3in Statesman?

This system keeps each cylinder bank on its own 3in pipe but finishes with two muffler stages instead of a hotdog resonator and a single muffler. The second muffler stage takes the note further down, making this the more reserved of the dual 3in WH Statesman builds. We publish no sound figure and won't quote one — but the twin-muffler choice is the quieter long-wheelbase setup.

What does the dual 3in routing give the Statesman?

Dual means the banks stay separate from the extractors back, each on its own 3in run the length of the car. That suits the wider, longer WH Statesman underbody. The 1¾in primaries feed both sides, replacing the factory cast manifolds with mandrel-bent tube-and-merge runners.

Will it suit my WH Statesman?

It's listed to fit the Holden WH Statesman V8. The long-wheelbase body and the dual twin-muffler routing are the checks here, so confirm your exact car with us against the listing before ordering.

Common questions

Is the SSMKHN0418 the quieter Statesman option?
It uses two muffler stages on a dual 3in layout rather than a hotdog, so it's the more reserved WH Statesman build. We don't publish a sound level.
Does it keep the banks separate?
Yes — dual 3in means each cylinder bank runs its own 3in pipe the length of the car.
