95 JGC Catalytic Converter
 

With 108K miles on it, I've noticed a rattle in the converter. I was under
there today and just giving the converter a gentle thump with the heal of my
hand, I can hear it. It's not like a bunch of broken pieces (like a ceramic
unit that's collapsed) but more like a large chunk of the guts moving around
a bit.

It runs fine, no overheating or any other bad signs.

Is this anything to be concerned about?

Thanks!
Dave

Yes. If it plugs up you will get excessive back pressure on the
engine. That will hurt your milage and isn't too good for the
engine. A failing cat also will shoo bits into the muffler which
causes all sorts of rattles. Also it won't clean the exhaust as
well, so depending on where you live you may not pass emissions.

A new cat from your basic muffler shop should run about 100$us installed
