Yes you can however is illegal in most states and will make the car where you CANNOT get smog,deq,inspection. Depending on your state can get you a fine and or jail time. Ebay is your best bet for a new one.


You may also get a check engine light for downstream O2 sensor.


just take the converter off, get a bypass pipe, and sell the expensive little metals inside it at a salvage yard- win, win! (you didn't hear this from me)
