    There are several threads on the use of mini cats especially those from big daddy’s. Use the search function and search for CEL’s

    My no cat headers threw a CEL straight away. Cheap 45 degree extenders fixed it permanently. Mini cats would have been next.

    F430s use wideband o2 sensors for both primary (fuel trim adaptations) and secondary (cat efficiency) and are much more sensitive to efficiency due to later emissions EU3/AU and us regulators than 360's. Later F430s are even stricter.

    My Ferrari SAK tool fully supports the F430s in this regard and works by either patching code so it will never ever generate a CEL, Period or Alternatively I can adjust sensitivity to be a lot less sensitive so CEL isn't going to trigger.

    These old analogue approaches are a bit hit and miss. Software recalibration or patching is the best way to go.
