If the engine runs rich the pellets will melt in the cat and eventually clog it. If your area requires annual emission testing it will get flagged if CO levels are too high. Worth a look, and of course you'll need to correct the rich burn before replacing the cat. Several counties in TX require emissions tests for all vehicles 2-24 years old, mine doesn't.

Just a thought.
