Hi guys, looking for some more help here. I am in the process of replacing all three CATs (2 precats and main cat). I ordered all three from Dayle at Motorsports and now I am thinking I should replace the oxygen sensors while I'm at it. They hook into the exhaust system. Although the oxygen sensors did not throw any codes prior to the car losing all its power, I can't help but think it may be wise to replace them. Dayle sells them for $100 each, Subaru dealer costs are almost three times that cost for OEMs. So I was thinking of ordering them with the other parts, or do you think I should just leave the original ones and see if they test out ok when the new cats are put on?
thanks for your help...
