Question: when instaling a new exhaust, what do you do with the o2 sensor? I plan on having a y pipe to strait 2.25" piping to my magnaflow. But do i make the y pipe after the o2 sensor, or do i relocate the o2 sensor into the new piping? Would it make any sense to leave some stock piping and then join y pipe after o2 sensor?
