However if you read the thread, and count..only 4 people actually posted that their high flow cats failed. Of those four, one was Kooks, one was SLP, one was ARH, and one was undetermined. I did not go to the trouble to see who they were tuned by, but that could be relevent. That is after 3500 views in this thread. So while a lot of people might claim to know someone who had cats fail, or heard a story, this thread makes it pretty obvious it is the exception, not the rule..and it can happen with any header set up.
Here are some more thoughts-
1- Callaway, SLP, and so forth do not sell their cars with LT headers because you can't sell a car new without factory cats. It will not pass most states initial inspection since headers relocate the cats and are for off road use only. SLP offers a new 600+ HP supercharger package on their website that includes their LT's with cats.
2- Preemptivly gutting your cats is nonsense. I have never seen a customer of mine, nor have I seen posted where a failed cat caused a motor to fail. Can it happen?..yes..but for it to happen you would have to ignore some pretty HUGE driveability issues. Cats have failed since the product was introduced..plenty of people have had it happen over the last 30 years. However often when you have seen it happen to do you recall a cars motor being blown? The odds must be astronomical, and even then are part the owners fauilt for ignoring obvious warning signs. When you mod cars, you have to balance out these different things. Yeah..there is a 1 in a million chance your cat could fail..and that could lead to somehow you ignoring it and blowing your motor. But there are plenty of other things with a much greater chance of failing. I mean hell..the stock oil pump toasted my supercharged motor..anything can happen.
The bottom line however is, gutting cats you paid $400 for because you heard somewhere that someone had them fail, and there is a 1 in a million chance if you ignore the warning signs your motor could blow is non sense. While the risk of failure is higher on a supercharged car (like any part really) assuming you have a decent tune, you have a good chance of your cats never failing or giving you an issue. On the outside chance they do fail, you should have plenty of warning in terms of drivability issues...they have a warranty..just get them replaced.
As for people talking about putting the stock manifolds/cats on over this issue..that is even crazier. Take off parts you paid good money for that work fine, to end up losing 60+ HP because there is a chance a part might break. The odds of your superchager breaking something very expensive in the engine or drivertrain is much higher than cats failing and causing signifigant damage. I don't see people taking their superchargers off.

I love how you post with information, supporting evidence, and logic. To bad other Vendors like Janetty couldn't follow your lead.
The purpose of a forum is to educate people, not badger whos got a bigger prick... Write that down Ted.
I'm siding with Maryland,
