skip buying a new sensor unless the old one is bad. i have an aftermarket cat as well. put the money into the simulator instead. it seems that a lot of aftermarket cats trip the dreaded p0420 code (on foreign cars as well) even though they would pass an emisions sniff test. i'm in MN and we don't have emmisions testing...
