The MPI Automotive MBM329MF is a 3in mandrel-bent sports rear muffler listed to fit the IRS V8 Ford Falcon sedan in the AU series. Mandrel bends keep the 3in bore at full diameter through the curves, so the gas path stays smooth where a crush-bent pipe would pinch — the detail that defines this sports-spec rear box.
Why mandrel-bent and 3in?
Mandrel bending forms each bend without collapsing the tube, holding the full 3in cross-section through the corners rather than necking down. Paired with the 3in bore — the wider size for a V8 opened up past stock — it makes for a freer-flowing rear section than a standard crush-bent muffler. As the rear box, it's also where most of the car's external note is shaped, with a sportier character than the factory part.
What does IRS fitment mean here?
This muffler is listed for the IRS (independent rear suspension) AU Falcon sedan, which routes pipework differently to the earlier live-axle cars. The IRS distinction governs how the rear section clears the suspension and where the hangers sit, so it's the detail to confirm against your exact car before fitting.
Will it suit my AU IRS V8, and how do we fit it?
It's listed to fit the IRS V8 Falcon sedan in the AU series; confirm your rear-end type and build with the workshop first. Oak Flats Muffler Men fits sports rear mufflers like this in-house in the Illawarra, checking IRS clearance, hangers and the 3in pipe alignment. MPI Automotive lists the MBM329MF at $463.80.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What makes the MBM329MF a sports muffler?
- It's a 3in mandrel-bent rear muffler, so the bends hold full bore for smoother flow and a sportier note than the factory crush-bent box.
- Is this for the live-axle or IRS Falcon?
- It's listed for the IRS AU Falcon sedan. Live-axle cars route differently, so confirm your rear-end type with the workshop.
