Ford Falcon AU V8 Sedan IRS Dual 2 1/2in Rear Muffler (SKU: MBM229MF) Engineered for selected vehicle.
Category: Mufflers and resonators


The MPI Automotive MBM229MF is a dual rear muffler listed to fit the IRS Ford Falcon AU V8 sedan. As the rearmost dual silencer, it sets the tailpipe note and is matched to the independent-rear-suspension floorpan.
A rear muffler is the last silencer before the tailpipe, so it has the most say in what you hear at the bumper. Running a dual layout means a muffler on each pipe of the twin system, quietening both banks of the V8 close to the exit. As chambered units they work by absorption and reflection inside the body, keeping cruise drone down while letting the V8 note through. It is the rear section only, paired with your centre and front pipework.
This part is listed for the IRS Ford Falcon AU V8 sedan. Independent rear suspension changes the rear floorpan and what the exhaust routes around compared with a live-axle car, so the dual rear is shaped to clear that IRS hardware and hang correctly. If your AU is a live-axle car, this is not the right listing — confirm your rear setup with the workshop before ordering.
It is built on a 2in bore, the supplier's figure for this listing and the only size we state. That matches the AU's twin rear pipework rather than a bigger-bore custom run. We do not state any measurement the record does not give, so confirm your pipe size with the workshop if your car has been modified.
Oak Flats Muffler Men fits Falcon dual rear mufflers in-house across the Illawarra. We mount both units to your AU's IRS hangers, check clearance to the suspension and tailpipe exit, and confirm the section lines up before booking you in.
