The Redback STR239TP is a performance rear muffler listed to fit the Ford Falcon AU with IRS. The independent-rear-suspension fitment is the key detail — this rear silencer is built to route and clear around the AU's IRS setup specifically.
Why the IRS fitment matters
An independent rear suspension changes what's under the back of the car compared with a live axle — the subframe, links and packaging are different, and the exhaust has to be routed and clearanced to suit. The STR239TP is the rear muffler built for the AU Falcon with IRS, so it mounts and clears around that setup rather than a live-axle car's. Getting the right one for your rear end is what keeps the tailpipe straight and rattle-free.
What the 'performance' rear muffler offers
Sold as a performance rear muffler, it's built to flow freer than a plain stock-style silencer at the back of the system — the last muffler before the tailpipe and the one that shapes the note. A freer-flowing muffler leans toward a fuller sound than the standard part while still quietening by absorption and reflection. The supplier lists no sound data, so we describe the character and quote no figures.
Will it suit my AU Falcon?
It's listed to fit the Ford Falcon AU with IRS. Confirm that your car actually runs IRS, plus your build, with the workshop before ordering — a live-axle AU takes a different rear muffler. We verify the rear setup against the listing before you commit.
Fitting at Oak Flats Muffler Men
Oak Flats Muffler Men supplies and fits the STR239TP across the Illawarra. We remove the old rear muffler, check the IRS-area hangers and the joint forward of it, and set the new unit so the tailpipe sits straight and clears the bodywork over the independent rear. We'll inspect the rest of the system on the hoist.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Why does the STR239TP specify IRS?
- Independent rear suspension changes the packaging at the back of the car, so this rear muffler is built to route and clear around the AU's IRS. A live-axle car needs a different part.
- Is it louder than standard?
- It's a performance rear muffler that flows freer than stock, so it leans toward a fuller note — still chambered, no published figures.
- How do I know if my AU has IRS?
- Tell us your build and we'll confirm the rear setup against the listing before you order.
