Ford Falcon AU V8 IRS SDN 2.5in Single With Extractors.
Category: Extractors and headers


Built around a single under-floor run, the MPI Automotive MKFD0057 is a 2.5in single extractor system listed to fit the Ford Falcon AU V8 IRS Sedan. The single-pipe layout suits the AU's independent-rear-suspension floor, taking tubular extractors at the heads into one 2.5in line.
Unlike a dual or L-and-R build, the MKFD0057 runs a single 2.5in pipe rearward. That single-line routing is matched to the Ford Falcon AU V8 with independent rear suspension, where the IRS cradle shapes the under-floor path. A 2.5in single run keeps the package simple and the bore sized for the street AU V8 rather than oversizing it.
Tubular extractors replace the factory cast manifolds with runners off each port, easing the merge at the heads. On the MKFD0057 they feed the single 2.5in system, making it a complete engine-back build rather than headers alone. The muffler arrangement isn't published in the supplier's listing for this part, so we'll confirm the rear silencing detail with you. There's no flow or sound data to quote — the value is the AU-IRS-specific routing and the matched single-pipe build.
It is listed to fit the Ford Falcon AU V8 IRS Sedan. The IRS qualifier matters — this is routed for the independent-rear AU, not the live-axle car. Confirm your exact AU build and rear-suspension type with the workshop before ordering.
