To start off i'm sure that my cat is toast but i also know that something in the engine has to clog it. I was driving and 3 miles down the road and they got cherry red. my question is what would be the cause of a clogged cat?
 
If it's running too rich the engine chucks out a load of soot, this can block up a cat. Check the airflow sensors are working correctly.
