i have a 2001 f-150 my cats are cloged and i dont want to spend an arm and a leg to replace them. I want to cut them off. In florida there isnt any test u have to pass or anything like that so i dont care about that. I want to know how to do it with out messing up my truck. Is there any o2 sensers that will bypass the cats and read right without them there or somthing anything.

 

Don't cut them off, ream them out....shouldn't mess up anythiing and it'll still LOOK like there are there.

 

If it were me I would install some magnaflow cats, one per side and it won't cost you an arm and a leg. If you cut them out you will have to get MIL eliminators so you dont get a check engine light from your O2 sensors.
