sti turbo back install/cel

so i just traded in my 06 wrx for an 05 sti about 2 weeks ago. it came with the borla hush cat back on it but it wasnt doing much for me so i ordered invidia n1 race cat back and v2 downpipe(no cats at all). a couple hours after the install i was taking 1st,2nd and 3rd gear up about the whole way on a back road just playing around and all of a sudden check engine light and my cruise is flashing. a friend said that since im not running any cats from the turbo back it could be the reason the cel came on a couple hours later since cat codes are 2 cycle or something but i dont really understand still. anyone have any input it would be much appreciated. thanks

btw im leaving to go to track in a couple hours to see what i run. im hoping 13 something but ill let you guys know. is running a bad idea with the cel?

The O2 sensor is throwing the CEL because of the elimination of the cats. The only time my cruise light flashes is when I reset the ECU though. Do you have EM?

With a TBE, I wouldn't race the car until you get some kind of EM, but that's just me. Better safe than sorry.
