Well some people need it because their CEL comes on when the cat is installed and never goes off. It is indeed a high flow cat so your computer might not like it. Try it out and see what happens.

the cheat is NOT needed, it is a fully functional cat and unless the o2 sensor was damaged, you should not have a problem

Sure a cheater is NOT needed but if you're throwing a code when you take it for emissions testing for your OBDII system then you're gonna have to do something. Either purchase the cheater or put your stock cat on for the day.
