Is there like an emissions warranty that may still cover this? Maybe the cats.?

Wetry, I called my local dealer hear in Fort Myers, Florida. They said the cat system is 8 years or 80,000 miles. Of course Kizzie will have to take it to the dealer to have it checked out. Of course Kizzie will be at the mercy of the dealer. OH, by the way it's a COLD 75 degrees here, yuk-yuk-yuk.
