I'm assuming that you have an O2 before and after the cat. If you install a high flow cat it may not satisfy your computer. If the O2 sensor doesn't read the gases it's suppose to it will keep popping the check engine light. I don't think reprogramming the computer will work either. There will be no manufacture code that will let you bypass emission standards. I would do the O2 simulator.
