I have not experienced�a clogged cat myself, but that is a common diagnosis for losing power.� Since the muffler is after the cat in the exhaust system what noise you do hear may be considerably less than would�be�heard�if the cat were not clogged. Since you need to yank that muffler anyway (when you get the time, of course), it should be easy to look into the end of the cat to determine if the honeycomb structure is broken up or out of place� Others may chime in with better troubleshooting than this.

Stephen, thanks.

I had not considered the cat. I do have a ruptured muffler and simply
haven't had the time to address so have been running it as is thought
it's a bit loud. Does the cat play into that?
