Ford Falcon AU V8 Ute 3in CatBack Muffler/Tailpipe.
Category: Mufflers and resonators


Built for the ute body, the MPI Automotive MKFD0078 is a 3in cat-back system listed to fit the AU Falcon V8 ute. It runs a rear muffler and finishes with a tailpipe, so it's the section behind the catalytic converter rather than a full engine-back replacement.
Tray-body Falcons route their exhaust differently to the sedans and wagons — the rear floor, chassis rails and tow gear all sit in different places, so the bends and hanger points are cut to suit a ute. This MKFD0078 is built around that layout in 3in pipe, with a single rear muffler and a tailpipe exit, which is why it's listed for the ute rather than shared across every AU body. The 3in bore suits the V8 it's matched to, giving the larger engine a freer path from the cat back than the factory pipework.
A cat-back replaces everything from the catalytic converter rearward — the over-axle pipe, the muffler and the tailpipe — while leaving the factory cat and the engine-side pipework in place. That keeps the emissions hardware the ute left the factory with, and the muffler here keeps the note civil rather than raucous. It's the common path for owners who want freer flow and a tidy rear section without touching the front of the system.
It's listed to fit the Ford Falcon AU V8 ute. AU utes came in several specs over the run, so send your exact build to the workshop and we'll confirm the hanger positions and tailpipe routing before ordering. Feed data can be imperfect, so we treat the listing as a starting point and check the vehicle on the hoist.
Oak Flats Muffler Men supplies and fits this MPI Automotive cat-back in-house. We mount it on the hoist, line up the 3in pipework against the factory hangers, set the muffler and tailpipe clearances, and check there's no contact with the tray or chassis before signing it off. The RRP is held against the MKFD0078 part as a special-order item; we'll confirm availability when you book.
