Angry Stock Cat Failure

Today I had to take my Z in for the 3 time to replace one of the cats. Last time both of them went out. My oxygen sensor also goes out each time also. I have an 06 enth. Has anyone else had this problem?

that shouldn't happen.

Are you running leaded gas or something other than pump-unleaded?

Do you have some insanely rich tune?

What do your spark plugs look like

I can't say I have ever heard of someone with this issue (aside from those running leaded race gas, but most who do that aren't using stock cats). Something isn't right.

Very unusual. I hope you are getting free catalytic converters.

No lead gas, just my daily driver. I don't drive crazy or anything either. No aftermarket mods.

does your check engine light come on?
I am just thinking what triggers you to find out that your Cats and O2 sensors have failed.
