bad cat?
Hey guys, just the other day I heard this pretty bad rattling coming from my exhaust. I think it was coming from the cat. It was very loud and sounded pretty bad. It just started suddenly too. Does this mean my cat went bad?
If i need to replace it, what would you guys recommend I use? Thanks in advance guys!

Re: bad cat?
You are most likely experiencing noise from a hanger that goes near the transmission mount. Look for some bolts to have loosened up and moved the hanger bracket.

Re: bad cat?
yeah it does that too. I tap it with the bottom of my palm and it rattles a bit. It sounds like its coming from inside the cat itsef, but I'll go and check the hangers again.
