Default "Question" HELP check engine light on

I put a set of test pipes on the z and they threw a code. So i put the spark plug defoulers on and the code is gone. About a month later it throws a code again. I took it to the nissan dealer ship and they fix it. They said that the o2 sensor by the exhaust was reading lean all the time. So he clears it and it goes back to running lean and then rich and cleared the codes. About a week later codes back. Any ideas NEED HELP. Should i go back to stock cat. I really dont want to do that. So can any body help me.
