If the Cat is worth $200 to a thief because of all the precious metals in it, how can a cheapo cat cost only $50?
The cheapo cat doesn't have many precious metals in, and barely is doing its job. The sniff test done at the annual inspection doesn't typically test for all types of gas. So probably the cheapo one might 'pass the test' but still be far from meeting the law.
Either that or the makers of cheapo knock-off catalytic converters have some amazing R&D that even the OEM's can't figure out...
