MPI Automotive Ford Falcon AU V8 Sedan IRS 3in Mandrel Bent Sports Front Muffler in S/Steel.
Category: Mufflers and resonators


The MPI Automotive SSMBM328MF is a 3in mandrel-bent sports front muffler in stainless steel for the IRS V8 Falcon AU sedan. It's the independent-rear counterpart: where the live-axle front muffler suits solid-axle cars, this one is matched to the AU's independent rear setup.
The IRS (independent rear suspension) AU Falcon carries its rear differently to the live-axle cars, and the exhaust routes around that geometry. This sports front muffler is the version matched to the IRS AU, so the system clears the independent rear setup. Fitting a live-axle part to an IRS car usually means clearance trouble, so this listing is specific to the independent-rear build.
The front muffler is the silencer nearest the engine, taking the first cut at the exhaust note before the gas reaches the rest of the system. As a sports unit it's tuned for a freer, harder note than a stock front box while still quietening. On the V8 AU it sets the early character of the note.
Mandrel bending keeps the 3in pipe at full bore through the curves so the larger pipe flows freely on the V8. Built in stainless it resists the corrosion that rots an aluminised system, and the 3in bore matches the airflow the V8 moves. It's a free-flowing, long-lived front section.
