If you remove the cat and still have the o2 sensor installed, itll still throw a code Maddog (itll throw the catalyst code as itll read the CC isnt doing its job). You have to spoof it whether the o2 sensor is installed or not (hence the spark plug trick).

Even SOME hi-flow cats will throw a code (I had a set that did on my Grand Prix), so they arent a guarantee, depends upon how sensitive the computer is and how well the hi-flow cat does.
