no CEL for catless downpipe

im seeing alot of members here getting cel for the o2 sensor after putting in a catless downpipe. I have jb4 with VRSF catless downpipe with a dorman 42009 spark plug non-fouler $6 (buy it at autozone/oreilly) installed with the rear 02 sensor. This had worked for me from the start and never received a cel. good luck.
