removeing cat converters
#2
Depends on the year of the vehicle. If it has OBDII the computer receives info from an O2 sensor after the converter to let the computer know the converter(s) is working as designed. Some models get fuel control from info after the converter. The 5.4s were not easy to squeeze out more HP.
