The MPI Automotive SSMKHN0290 is the hotdog-resonator take on the dual 2.5in WH Statesman system — twin 2.5in pipes the length of the long-wheelbase car, each carrying a hotdog ahead of its muffler. It's listed to fit the Holden WH Statesman V8.

Where does the hotdog build sit for the WH Statesman?

This dual 2.5in system runs a hotdog resonator before each muffler rather than a single muffler-and-tailpipe or a full twin-muffler exit. The hotdog takes an early edge off the note mid-section, then the muffler finishes — a middle path between the more open and the quietest WH Statesman builds. No sound figure is published; we won't quote one.

What does dual 2.5in routing give the long-wheelbase car?

Dual keeps each cylinder bank on its own 2.5in pipe to the rear, suiting the longer WH Statesman underbody. At 2.5in the bore keeps gas speed up for street response, and the extractors replace 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 hotdog routing are the checks here, so confirm your exact car with us against the listing before ordering.

We check the extractor flanges to your heads, route both 2.5in pipes the length of the car, hang the hotdog and muffler each side and seal the joints for heat cycling. RRP is listed at 4527.01 AUD; fitting is quoted once we've seen the car.

Common questions

How does the SSMKHN0290 differ from the muffler-and-tailpipe WH version?
It runs a hotdog resonator into a muffler each side rather than a single muffler-and-tailpipe, so it sits between the open and the quietest WH Statesman builds on note.
Does each bank run its own pipe?
Yes — dual 2.5in means separate left and right 2.5in pipes the length of the car.
