Your Honda dealer is wanting your money. your converter might be fine. What is happening is your post cat 02 sensor is either bias or slow. This O2 sensor responds to the oxygen left over after the cat. I would have this 02 sensor checked before replacing the cat. Which by the way is what they should of done.

$5 says its the 02 sensor, but if the cat is infact bad ask them to test the pre 02 sensor before you repl the cat. If your pre 02 is bad it will take out the cat.

Gotta luv a warranty
