I have been seeing some questions pop up asking about catalytic converters, thought I would post up some facts for you kids 
First off, you have to make sure that you have the correct type of converter for your car. If your car is OBD I compliant, you can use any EPA or CARB approved OBD I converter. If your car is OBD II compliant, your cat must be OBD II approved. As a general rule, any car 1996 or newer is OBD II and any car 1995 or older is OBD I. However, some cars were OBD II compliant as early as 1994, so double-check the under-hood emissions sticker. The difference between OBD I and OBD II cats is actually huge.
OBD II cats are required to remove 90 percent of emissions, while the OBD I cats are only required to remove 70 percent.
With this being said, lets say you install an OBDI instead of OBDII, your going to fail emissions
The purpose of a catalytic converter is to clean up the exhaust gases or Hydrocarbons if you want to get technical, taking out your cat in most states is illegal in California they impound and crush your car the next day, the laws are strict for good reason
I am a big cat fan, there is no absolute proof as to them hurting performance, or making it hard to tune.
Thanks for reading my huge post.
