Exactly what I was thinking when I started reading this thread. Wonder what would happen if it is a major issue that has just started to show its fugly head.

Add a Supercharger with Say 7-8 PSI they 6.2 Liter Engine just became 9.3 Liters which far exceeds the Cat Design which causes Overheating and Failure.

The Cats need to be Double they're current Size to handle the Additional cubic inches.

I read your reply and wanted to know being in the performance business do you know of such types of cats for a larger engine to work with the setup for the 2010-12 Camaro exhaust? I have not looked anywhere yet but have just read through this thread and started to wonder about it.

HF Cats

After reading this I need to do something so what are my options? Besides gutting the cats, if i put the oem cats and exhaust back on will I be okay. I know it will cost me HP but how much?

I don't really really think there are any options besides going with mid pipes without cats, but that's for off-road and illegal. If you were to put the stock cats on, I would assume they may blow out even quicker, but don't know.

Anyone know if the stock cats last less time than the high flows in terms of longevity on boosted vehicles, or are the stock cats more robust?

OK, after reading this thread I was, to put it lightly, officially freaked. For my wife's M6 Eforce Camaro, with JRE fuel upgrade and injectors, stock cats, hand ported and ceramic coated exhaust manifolds (by me), Thunder Racing V3 cam, Vmax ported TB, and tune, we have coaxed 585 RWHP. I dont consider myself an expert on internal combustion engines by any means but I do read alot and implement what I read in an engineering fashion. As the "gearhead of the office" this completely caught me off guard. I have encouraged a fellow co-worker down the 2010 Camaro FI road along with myself, have advised G8 owners on viable performance options and am currently assisting a grad student in his studies and understanding of internal combustion engines with regards to cam timing, head flow, CR, etc.
I think that Ted said it best with FI = more "effective" cubic inches than stock.
Bottom line is that I ordered the JBA non-catted straight pipe to replace the cats that are currently installed.
I have noticed that the car "just doesn't seem to have to power that it used to have". Although we all suffer from this mallady, the car does truly seem to have lost power and has only been driven 2k miles since the SC/cam install. Once the pipes arrive this week (hopefully), I will post pics of what I'm removing in order to circumvent a potentially catastrophic outcome.
Thanks.

I've had my Magnaflow High Flow Cats on along with my Maggie for the past 20,000 miles. I had my exhaust guy check my cats for burnout per Ten Jannetty's advice and all was clear. No damage at the time. I'll continue to check them annually to be safe. I'm about 550rwhp. Keeping my fingers crossed. We'll see. No opinion here.

I called ARH to ask them about this, since they make high flow cats. I talked with Mike, and he said that it was really up to the tune. Too rich, and they will burn up. However, it seems to me that Ted is right also. It is probably a combination of the two. If you have more volume, you'll have more heat. If you have more excess fuel, you'll have more heat.

I would like a safe catted solution. I don't see that happening real soon since nobody is working on a solution.

Sorry to butt in. Are the stock cats on the ZL-1 the same cats on the SS? If they are than that is a safe bet they are of a much better quality than these Hi-Flow cats that are burning up. Correct me if I am wrong.
So, 5-9 PSI is safe, more you need mid-pipes?

I talked to Kooks about this. They said their cats will hold up to supercharged applications. Said they've installed superchargers on camaor's with their exhaust. Has anyone had any problems with the Kooks high flow cats?

From what I have seen most issues have been with Kooks. That is what I have on mine and I will be taking them off, I do not want to take any chances, I talked to the guy yesterday that had tuned my car, and he recommended removing them and said it would not affect my tune, just mak the car a little louder.

We have seen several sets of Kooks Cats Fail with superchargers.

Bummer... I might not have spent the extra cash knowing this "might" happen even though I'm not going for much more HP than I have now. :( Seems like an asterisk is needed on these HF cats when FI is involved.
