I think my cat is finally gone. The rattle coming from it is so loud. I can hear it during idle and it gets worse when I hit the gas pedal. I read the manual and the warranty covers it up to 80k miles. Go figure. I have SLP exhaust. Do you guys think this better flowing exhaust damaged the cat? I thought cats last a lot longer.

I've replaced cats on some cars with around 50k miles on them. Should they last longer... Ya, but bot everything works the way it is supposed to. No I dont think the slp had anything to do with it.
