spotting a dodgy cat
is there any way of visually identifying a catalytic converter thats given up?
ie is it very obvious when they fail.. do they appear melted or something similarly drastic?
just looking at mine and it appears as a fairly normal greyish honeycomb. a fair few cells are blocked. what do you think?
 
is it toast?

Usually they look perfect.
That one is well past its best well choked - not only will it cause a lot of back pressure but it will be very inefficient at its job.
Even a new cat causes a lot of back presure.
The other main failure mode breaking up it is usually because of severe missfire or physical accident damage.
