I was going to replace my exhaust with a custom setup from magnaflow. I am going to put a muffler and a cat. converter on it. I will have 2.5 pipe ran all the way back. This is my question. I have heard that I might need a sensor from PFYC so that my service engine soon light will not come on. I read that it had something to do with a 02 sensor. Can somebody tell me were they (02) all are and do I need this little box?

You might need it, depends on the converter you get. Some trip the lgiht, some don't. The sensor that it replaces is just after the cat, underneath your car.
