My car was making this wierd rattling noise coming off throttle and at idle. sounded really bad, like a heat shield or maybe even something internally wrong.
2 opinions from other jetters was that the cat might be falling apart inside, so we set to take it off and have a look.
This is what we found:
That's right, a little tiny nugget of the cat material left. Just a nearly perfect round ball rattling around in there.
I cracked it in half and it fell out. Easiest cat gutting I've ever seen.
