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


The MPI Automotive SSMKFD0255 is a cat-delete turbo-back exhaust listed to fit the Ford Ranger 3.2L (PX2 and PX3). It drops the catalytic converter but keeps a rear muffler, so the gas path opens right up while the tail-pipe note stays on the civil side of loud.
Removing the catalytic converter takes out one of the larger flow restrictions between the turbo and the tail-pipe, which is exactly why MPI offers this SSMKFD0255 as the without-cat variant of the PX-series turbo-back family. The trade-off is a legal one rather than a fitment one: the converter is emissions hardware, and pulling it changes what the Ranger is allowed to do on the road. Because it keeps a rear muffler rather than running open, the note stays muted compared with a straight-through layout, so it reads as a free-flowing diesel rather than a raucous one.
A turbo-back replaces the exhaust from the turbo outlet all the way to the tail, the full diesel span rather than a tailpipe-only swap. On this build the rear muffler does the quietening through absorption and reflection, so you get the bigger pipe without the bark of a no-muffler system. It is the middle path in the range — more open than a with-cat car, but tamer than a hotdog or straight-through alternative.
No — because the SSMKFD0255 deletes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road and competition use only. That is the honest position on any cat-delete diesel system; there is no softening of it. Talk to the workshop about your intended use before committing.
It is listed to fit the Ford Ranger 3.2L in PX2 and PX3 guise; confirm the exact build with the workshop, since cab and model-year details vary across the run.
