I am trying to purchase headers for my 95 Honda Accord dx. The main thing I cant figure out is whether or not I have to connect the airflow sensor or the o2 sensor to the manifold. I looked a my stock one and there is a wire or line or someting like that coming out of the exhaust manifold. How can I take this off and is it going to be hard to put it on the new one? I am also curious whether I even need the airflow sensor because wont that just restrict the airflow? What will happen if I dont reconnect it?































Thanks in advance
