The MPI Automotive SSMKHN0138 is the hotdog-and-muffler 3in dual cat-back for the VY V8 HSV sedan. A compact straight-through hotdog ahead of the muffler is its signature: it keeps the dual run breathing more freely than a twin-chamber build.

What does the hotdog change on the HSV?

A hotdog is a short straight-through resonator — gas runs through a perforated core, trimming drone without the restriction of a full chamber. With a single muffler behind it, the VY HSV sedan gets a freer-breathing rear half, while the muffler keeps peak volume in check so the note stays managed.

What does the dual cat-back cover?

It replaces the exhaust from the catalytic converter rearward in two pipes routed down the VY sedan floor. The factory cat stays in place, so this is the rear-half change and the emissions equipment ahead of the cat is left standard.

Will it suit my VY HSV V8 sedan?

It is listed to fit the VY V8 HSV sedan; the supplier does not publish a year. We treat the listing as a guide rather than a guarantee and confirm the hotdog and muffler routing against your actual HSV before ordering the part in.

Who fits it, and what does it cost?

Oak Flats Muffler Men supplies and fits this MPI Automotive cat-back across the Illawarra, lining up the hotdog and muffler, the dual run and the hanger positions against your HSV sedan before booking the bay. As a cat-back it keeps the factory cat in place. RRP is $2,465.58; as an MPI Automotive part it is ordered in for your car.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
