MPI Automotive Mazda BT50 B32P 3.2L Without Cat.
Category: Complete exhaust systems


The MPI Automotive SSMKMA0006 is the without-cat exhaust system for the 3.2L Mazda BT-50 (B32P), listed at $2,084.35 AUD. This is the catless build, the counterpart to the with-cat 3.2L listing.
This part is the 3.2L Mazda BT-50, carrying the B32P code, supplied without a catalytic converter. The without-cat configuration is the defining detail and the reason it sits below the with-cat 3.2L option in price. MPI Automotive lists it as a complete system; the diameter and material are not published, so the build is confirmed against your truck rather than quoted from the listing.
A complete system replaces the underbody run as one matched set from front to tailpipe. On the catless version the catalytic converter is left out of that run, which alters how the vehicle reads on an emissions check — the rest of the system is still a full, properly sized replacement. It is a build chosen for specific uses, not a like-for-like factory replacement.
Because the converter is omitted, the emissions hardware the BT-50 left the factory with is not part of this kit, which matters for registration — confirm your state's requirements with us before ordering. Owners who need to keep the vehicle road-registered should look at the matching with-cat 3.2L BT-50 listing instead.
