1991 SC Exhaust

I read somewhere that a 1991 Thunderbird SC has OBDII which will put the vehicle into LOS (limited operation strategy) aka limp-home mode is this true? I plan to cut my cats out, and install a flowmaster cat-back system with their resonator. If the vehicle is equipped with OBDII, how do I prevent it from going into LOS with the cats gone?
System I plan to install:

Any sensors should be before the cats so you shouldn't have to worry about anything.
