I'm thinking about replacing my stock muffler. It has this weird droning sound inside the cab gets on my nerves. However, I really don't wanna do it if the cat will fail later. I had a cat on my old 88 XJ and it failed at around 110K so I just replaced the whole exhaust at once. My 2000 has about 73K on it. Does the new system last longer than earlier models?
