i bought a Catco direct-fit cat about 4 months ago, maybe even less. and now it's cooked. the internals are no where to be found, so it's pretty much a test pipe as it stands now.
i know having a misfire long enough will cook a cat, but i'm not missing. any other reasons why a cat can just blow out like that?
i started to notice the louder sound when/after my cb died on the highway due to a bad ignitor/coil. once i replaced the distributor, the exhaust note was noticeably louder. i put the car on a lift and banged around the cat and it sounded hollow as shit, so i took it off and boom, nothing inside at all.
