Does the RPC4537 fit my BA or BF Falcon?

It's listed to fit the Ford Falcon BA and BF in sedan, wagon and ute, suiting the factory manifold. Confirm your exact body and setup with the workshop first.

Does this remove the catalytic converter?

No — the RPC4537 is itself a high-flow catalytic converter, so it keeps a cat in the exhaust rather than deleting one.

The Redback RPC4537 lists at $307 RRP. Contact Oak Flats Muffler Men to confirm availability and book fitting.

The Redback RPC4537 is a high-flow catalytic converter listed to fit the Ford Falcon BA and BF in sedan, wagon and ute, suiting the factory manifold. It's the cat-stage part of the exhaust, with a Redback RRP of $307.

What is a high-flow cat and what does it change?

A catalytic converter is the emissions device that sits in the exhaust to treat the gases before they leave the system. A high-flow cat is a converter built with less internal restriction than a heavily blocked or aged factory unit, so it's the part you fit when you want the converter in place but flowing more freely. The RPC4537 is listed to suit the factory manifold on the BA/BF Falcon, meaning it ties into the standard manifold rather than aftermarket headers. The supplier doesn't publish cell count or material in this listing, so those are confirmed on the part rather than assumed.

Will it suit my BA or BF Falcon?

This converter is listed to fit the Ford Falcon BA and BF across sedan, wagon and ute bodies, and is designed to suit the factory manifold. The main check is that your car still runs the standard manifold the listing expects, rather than an aftermarket header setup, and that you match the BA/BF application. Treat it as 'listed to fit' and confirm your exact body and configuration with the workshop before ordering.

Is it road legal?

Because the RPC4537 is itself a catalytic converter rather than a cat-delete, it keeps emissions hardware in the exhaust — the opposite of removing the cat. Even so, road compliance depends on the specific converter meeting the requirements for your vehicle, so we don't claim blanket legality here. Confirm the exact part and any NSW registration requirements with the workshop before fitting.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits high-flow cats like the RPC4537 in-house across the Illawarra. On a BA/BF Falcon that means confirming it ties to your factory manifold, checking the flange and pipe alignment, and making sure it sits cleanly in the existing system before we book the bay.
