Ford Falcon AU 6 Cyl / V8 IRS Sedan Rear Muffler (SKU: MBM386MF) Engineered for selected vehicle.
Category: Mufflers and resonators


The MPI Automotive MBM386MF is a rear muffler listed to fit the Ford Falcon AU sedan with independent rear suspension, in both six-cylinder and V8 form. The IRS sedan fitment is what defines it — it's shaped to the AU's independent rear end and covers both engine lines.
The AU introduced independent rear suspension on the Falcon, which changed the room and routing at the back of the car versus the older live axle. A rear muffler for that car has to clear the IRS cradle and its links, so the MBM386MF is listed specifically for the IRS sedan. Fitting the right body-and-suspension match means it sits on the factory hangers without fouling the rear end.
As the last silencer in the system, the rear muffler sets the cruise and idle note you hear behind the car. Replacing it refreshes a tired factory unit or alters the back-of-the-car tone without touching the rest of the exhaust. It quietens by chambered absorption rather than by choking flow. The supplier doesn't publish a bore figure for this part, so we'll confirm the pipe size against your system at fitting.
It's listed for the AU IRS sedan in both six-cylinder and V8 form, so it suits the bulk of the AU sedan range with independent rear suspension. Send your exact engine and build and we'll confirm the rear section match before ordering.
Oak Flats Muffler Men fits the MBM386MF in-house, confirming the IRS sedan build and setting the muffler clear of the rear cradle on its hangers. Book the car in and we'll match it to your VIN.
