A comment about welding on catalytic converters was made and to this I
say:You can weld them on but it will do you no good.
I work for A police dept. (steam engineer/building maintenance) and
the cops catch the perps all the time. In there possession is A battery
powered sawzall or A hacksaw. In our maintenance shop we have 5 or 6
cats( we sell them when we get enough to make A scrap run worthwhile)
and all of them have been sawed off. If A socket or wrench was used to
remove the clamps the perp would still need to wrestle the thing off the
exhaust system and that takes too long. They want to get under and out
with there ill gotten gains as fast as possible.
