What can ruin a catalytic converter?
- Oil (if the engine burns oil)
- Tetraethyl lead (leaded petrol, some people still use leaded avgas in old cars due to the high octane and valve seat protection)

What is a catalytic converter?
Catalytic converters clean exhaust gases of harmful chemicals and gases that pollute the atmosphere. However, they also restrict the free flow of exhaust and suck power from a car. Most high performance enthusiasts install a high flow converter that eliminates this restriction as much as possible while still cleaning exhaust gases.
How to remove catalyst from car?
The simplest and cheapest way to remove the catalyst is simply to gut your converter. Get the car on a lift or stands or however you choose to get under it and unbolt the converter. Be sure to do this after the car has been off for several hours, as exhaust piping can remain hot for quite some time. Also, the heat will cause the metal to expand, making it more difficult to remove. Once you've removed the converter, the catalyst will look like a honeycomb on the inside. It's solid and tough to remove, but using a crowbar as a chisel and a hammer, you can break it out. It can be a slow going process to remove all of it, but the process can be aided by using a drill with a long bit to start weakening the honeycomb structure, which is very sturdy. Once all of the catalyst is removed, replace the empty converter shell and your car is good to go. There are, however, problems with doing this. Removing the catalyst not only makes your car illegal for street use, but the empty shell of the converter is a good deal wider than the rest of the exhaust system. This causes problems with pressure changes and velocity inconsistency which can actually negatively impact the performance of your car rather than enhance it.
