MPI Automotive Holden VZ V8 Monaro 2.5in Dual Catback Hotdog/Muffler.
Category: Mufflers and resonators


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.
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.
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.
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.
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.
