Catalytic converter bypass

My Liberty started to rapidly lose power. I ran the codes, o2 sensor. I replaced the o2 sensor and it ran good for a day or 2. Same lose of power, sputtering came back. Did more digging.. cats were bad. Too expensive to replace, so I cut them off and welded in straight pipe. Ran great for a day or 2 then the same problem came back. Should I keep replacing o2 sensors or is there something else I can try? Any advice is appreciated. Thanks.
