I saw Chef's car while I was there getting my car tuned again. That HFC was melted no doubt. If you ever looked into one, and see it all wrapped in there, this was like in a black ball, all inside of it. No way to even get it out if he wanted too.
IMHO that cat came loose from the sides and started to come apart. That to me is a quality issue of the cats themselves. But at least with TPs you got it solved. I had them turn off my O2 sensors to not throw codes anymore if I wanted to go to TP eventually.

Interesting story... Thanks for keeping up with everything and letting us know what was going on...
I've had Crawford high flow cats for two years... I've never noticed anything odd about them, but your post makes me think I at least want to check them out.
Did your exhaust make different sounds on the two different pipes? Was driver's side exhaust quieter for instance?

I really have no idea how this happend and when. I also really wants to know. Since compression test has been done before dyno and Ultimate racing told me if metal cat melted down, car ran really lean which means bad for engine. I really hope this happend before compression test.
I asked jared to keep that HFC on the side, so i can look at it. I will post up pictures once i receive it.

Best run was 425 on their dyno, and jared is still tunning it. Now sounds about right. 
Also, jared cut down a lot $ from my final bill...
