The MPI Automotive SSMKHN0155 is a 2.5in dual cat-back with a hotdog resonator, listed to fit the Holden VZ V8 Monaro. The dual-pipe layout is the angle here — two 2.5in banks down the rear give the Monaro's V8 a balanced, twin-exit flow path.

Why a dual 2.5in setup?

A dual layout splits the flow into two 2.5in banks rather than running a single larger pipe, which suits a V8 coupe like the Monaro where the rear can carry twin exits. Twin 2.5in keeps gas speed up on each side while still moving the volume a V8 produces. We state only the 2.5in diameter MPI lists — there's no figure for combined area, so we don't guess one.

What does the hotdog add?

Each bank carries a hotdog — a compact straight-through resonator that flows freely and gives a harder note than a chambered muffler. On a dual Monaro system it sharpens the V8 character through twin exits without the bulk of full mufflers. Sound is described by type here; MPI publishes no decibel data.

Does it fit my VZ Monaro?

The SSMKHN0155 is listed to fit the Holden VZ V8 Monaro. The Monaro's two-door rear and dual routing are specific, so confirm your exact build and rear-end layout with the workshop before ordering to be sure the twin exits and hangers line up.

What's fitting like at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this MPI dual section in-house across the Illawarra. We check both banks' flanges, hangers and tailpipe clearance against your Monaro first. It's usually a special order — send your build and we'll confirm stock and timing.
