The MPI Automotive MKHN0133 is a 2.5in dual cat-back with a hotdog muffler, listed to fit the V8 VY HSV sedan. Built for the VY series specifically, it leads with the straight-through hotdog resonator — a free-flowing voice on the twin 2.5in run.

What is the hotdog doing in this system?

The hotdog is a compact straight-through resonator: exhaust runs down a perforated core rather than through chambers, so it flows freely and gives a harder note than a chambered muffler. On the V8 VY HSV sedan it suits an owner who wants more presence from the cat-back. It is a tuning device rather than a silencer.

Why a 2.5in dual layout?

It is a 2.5in cat-back in a dual configuration, sized for the V8 and routed as a twin system. The 2.5in figure is the only diameter stated in this listing; the workshop confirms the hotdog and tailpipe positions against the VY sedan's rear floor rather than assuming them.

Will it suit my VY HSV sedan?

It is listed to fit the V8 HSV sedan on the VY series specifically. The supplier publishes no model years for this part, so confirm your exact build with the workshop before ordering rather than relying on the badge.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits this MPI Automotive cat-back in-house across the Illawarra. We check the hotdog and tailpipe sit clear of the rear floor, confirm the hangers, and mount it square. Send your build and we will confirm fitment and book the bay.

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