Ford PX2 & PX3 Ranger 3.2L Turbo Back With Cat & Without Muffler.
Category: Mufflers and resonators


Keeping the catalytic converter while deleting the muffler is what sets the MPI Automotive SSMKFD0273 apart — a turbo-back listed to fit the Ford Ranger PX2 and PX3 3.2L. The cat stays in, but the muffler comes out, so it's the louder build that still retains the emissions hardware.
This SKU keeps the catalytic converter in place but runs without a muffler. That gives a freer, fuller note than a fully muffled system because there's no chambered silencing in the run, while the cat continues to handle the emissions side. It's the middle ground in this PX2/PX3 family: more voice than a muffled build, but with the emissions hardware the ute left the factory with still fitted.
On a 3.2L diesel the catalytic converter is the emissions device that road compliance hinges on. Leaving it in, as the SSMKFD0273 does, keeps the Ranger closer to factory emissions behaviour and avoids the off-road-only restrictions a cat-delete carries — even though this build drops the muffler for a louder result.
Because this turbo-back retains the catalytic converter, the key emissions equipment stays in the system rather than being removed. Removing a muffler changes the note, not the emissions hardware. Confirm the exact build and any current state requirements with the workshop before fitting, since rules and individual setups vary.
