The MPI Automotive SSMKHN0137 is a 3in dual cat-back for the VY V8 HSV sedan running twin mufflers. The muffler-plus-muffler layout is what defines it: two chambered boxes for the most settled note on the HSV-spec sedan.

Why two mufflers on the HSV sedan?

This SSMKHN0137 carries a chambered muffler on each side of the dual run. Two absorptive boxes reflect and damp more than a resonator setup, so the VY HSV sedan keeps a deep but disciplined note — the choice for an owner who wants the V8 present without it droning on the highway.

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, keeping the factory cat. The emissions hardware ahead of the cat is untouched, so this is the rear-half upgrade.

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 dual routing and both muffler positions against your actual HSV before ordering the part in.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this MPI Automotive cat-back across the Illawarra, lining up both mufflers, 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, so the emissions hardware ahead of it is untouched. RRP is $2,539.79 and 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.
