Eliminating cat CEL.....

[Spaniel1287]

I am about to do my exhaust and I planned on taking out my cat converter. I was told that once I take that out that it will throw a CEL becuase of the rear o2 Sensor. You guys familiar with this and what do i do so the CEL wont come on?

I believe VFAQ.Com has info. on this. I used that circuit with one modification. It calls for a 12 ohm, 12 watt resistor to simulate the heater. I used a 25 watt, and it still got hot enough to melt the solder joint. I used a 50 ohm/25watt and all is cool. No CEL.

Weld an O2 bung into the pipe itself.

and how exactly will "welding an o2 bung in the pipe itself" help get rid of a CEL from there being no cat?
