Ford Falcon AU V8 IRS SDN 2.5in Dual Catback Muffler (SKU: SSMKFD0064) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive SSMKFD0064 is a dual 2.5in cat-back built specifically for the AU Ford Falcon V8 sedan with the IRS rear end. The independent-rear-suspension routing is what makes this listing its own part — the rear section has to thread around the IRS cradle rather than a live axle, so it isn't interchangeable with a solid-axle sedan's pipework.
An independent rear suspension Falcon packages its rear pipes around a subframe and driveshafts that sit differently to a live-axle car. That changes the bends and hanger positions over the back of the system, which is why this dual 2.5in cat-back is listed for the IRS sedan specifically. Getting that routing right is the difference between a system that clears everything and one that fouls suspension movement.
A cat-back replaces everything from the catalytic converter back. Running two 2.5in pipes gives each bank of the V8 its own path at a bore that keeps gas speed sensible for a street sedan, finishing through a muffler to keep the note liveable. It's a flow upgrade on the factory system rather than an all-out loud setup.
It's listed to fit the Ford Falcon V8 sedan with IRS in AU guise. Because the rear routing is IRS-specific, confirming your car actually has the IRS rear matters here more than usual — the workshop can verify your build before you order.
