It was a Magnaflow cat that I've had about 8 years. I've had good luck with that brand with mufflers, but I am disappointed with the cat failure. It might have seen a little more vibration than a stock vehicle, but not abuse. I bought the identical part number again and will hope to get at least 8 years out of it. I do need to pass emissions. I am also a closet greenie.
