So my service engine soon light came on today. My friend ran a scan on it and it is my O2 sensor. I have a high flow cat why would I be getting this issue? I went with a cat and not a test pipe so I wouldn't have to deal with this problem. What do you think that I should do?

There shouldn't be, but you can check beforehand based on the angle of the O2 sensor's position. Just take a ruler or something to see if the additional length of the anti-fouler plug will give you a problem. If the hfc you bought was made specifically for the EVO, then you shouldn't have a problem - my tp from the Tanabe exhaust sys was made specifically for the EVO, so I didn't have any clearance issue with mine.
