    Hey there! I just replaced my front A/F sensor and the old one looked soooo bad, super black! Changed it and instantly felt a difference in how it ran and also feels quicker.:)

    But my question is, Is it a good idea to change the rear one as well? It probably is, but just checkin. Also, do headers make cats good bad quicker? Thanks!
