The MPI Automotive MKFD0055 is a full-length exhaust system listed to fit the AU Falcon six-cylinder IRS sedan, not just the back section. It runs two muffler stages end to end, replacing the run rather than tacking onto the factory rear.

What does a full system cover versus a cat-back?

Where a cat-back only swaps the rear section, a full system replaces a longer span of the exhaust in one matched run — which is why the MKFD0055 sits at the top of the AU range on price. It carries two muffler stages, so the note is kept controlled along the whole line rather than relying on a single rear silencer. The supplier hasn't published a single bore figure for this listing, so we confirm pipe sizing against your car at fitting.

Why the six-cylinder IRS sedan specifically?

This is built for the AU's straight-six sedan with independent rear suspension. The IRS cradle and over-axle geometry differ from the live-axle cars, and a six routes and packages differently to a V8, so the full system is cut to suit that exact combination. That's why it carries its own part number and isn't shared with the V8 or wagon variants.

Will it suit my AU sedan?

It's listed to fit the Ford Falcon AU six-cylinder IRS sedan. AU sedans ran both live-axle and IRS rear ends, so the IRS detail matters — send your exact build to the workshop and we'll confirm the rear end and hanger points before ordering. Feed data can be imperfect, so we verify the car on the hoist first.

What does fitting a full system involve in Illawarra?

A full system is a bigger job than a rear-only swap, and Oak Flats Muffler Men fits it in-house. We mount the complete run on the hoist, set both mufflers and the connecting pipework for clearance against the IRS rear and floor, and check the whole line hangs clean before sign-off. The MKFD0055 is held at its listed RRP as a special-order item; we'll confirm lead time when you book.
