Around how much would it cost to replace a catalytic converter in 1999 ford escort, with parts and labor? Just need an estimate so i know what ill be dealing with! Thanks! 
What has caused you to think you need a convertor? In Feb. you had the service engine light on but never posted the codes. Are these related?

It’ll give you some idea what it will cost to replace the cat.

This is a very old car, replacing the cat alone may allow you to use a “universal” one costing about $100 for the part and about another $100 for labor for a total of $200. Rough guess. Replacing the complete assembly with pipes and flanges may add as much as another $100.
Do you live in a state w/pretty strict emissions testing? If so make sure the replacement cat meets the state’s requirements. Here in Calif replacing a cat on a 99 Escort, assuming there’s just one cat involved, I’d guess that would come to close to $750 parts and labor. Make sure you shop figures out what made you cat fail, misfiring, air fuel mixture problem, or whatever, otherwise the new one will fail too.
