i put a new custom 2.5"dp along with a new cat and i was wondering if my rear o2 sensor is still good because the number is super low.
the number i get from my rear o2 sensor is 0.060-0.080 and the line on the graph is at the bottom going straight across only. I notice upon 1st start up the rear o2 sensor says 0.60-0.66 but after it warms up its back to 0.060-0.080.. i got a new catco cat so is my rear o2 sensor bad now?
