I did check the warranty on the cat. It expired this March. Even so. It's likely it would. To have been covered if any of these applied. The cat shell appeared bluish. If the cat smelled like gas or the cat had soot build up. But, it doesn't matter. The 8 years was up in march. I need a new left side cat. So, if you guys know of a good used one with headers. Please let me know. Thanks.
