Rear cat ?

whats up guys, so iv had my jeep since about august, got it inspected went through that whole deal and i get a test run on my jeep to make sure everything is good. they tell me my rear cat converter isnt 100% but say that its not a problem but just to keep an eye on it. ever since my check engine light has been on because of it. it recently went off the other day, and has been off ever since. im wondering what kind of problems i could run into if i dont get it fixed or if it will take away horse power or anything! Help me out!

Have had to replace a total of 3 cats-only "paid" for the first one. I believe that what was causing the problems with the ones I got was wrong octane-was buying premium with the thought it would make Jeep "run better" not true. When the cat-s went I suddenly had no power -after they were replaced it showed that it was slowly plugging up but didn't realize until all at once it was plugged. IDK if the couple hundred not to big an issue may want to go ahead and change it since it caused the code? Maybe it caused the code maybe something else? Wondering if the PO may have ran premium-sometimes? Or you have? Good luck!!

do you still run premium? if not have you noticed a change at all? minus the fact that your wallet is a little more empty haha.
