Catalytic Converter

[Kyle]

I have put 3 of them on my car and now the 3rd one is going bad. My question is why are they all going bad so fast???

How many miles do you have on the car and about how many miles are you getting between converters?

If the engine is bad with misfires or burning coolant or oil it will trash the cat.

I am sure it is not doing any of those things.
