I got a set off bbk lt's and a mid pipe with magnaflow high flow cats, and after a month of being on the car both cats blew out... all the stuff inside them is now in my mufflers and stuck in my exhaust pipes. Anyone have any guesses as to why 2 cats would just fall apart like this?

My friend had magnaflow cats on his 2.2 cavalier and they blew out in three weeks. They warrented him like 6 times before his said the hell with this and went catless.
