I just got my UPR offroad X-pipe installed today. One of my front 02 sensors and one of my rear 02 sensors were stripped when the exhaust shop took them out of the old H-pipe. The guy did not put the two stripped 02 sensors back in and just plugged the holes on the x-pipe. The car is idling a little rough and i'm assuming its because i'm missing a front sensor. I have a tune coming that will turn off the rear sensors.

My question is, should i replace both 02 sensors, or just leave the rear one plugged and get a new front one?

 

get a new front one
