I'm getting a vibrating sound from what I believe is from the exhaust when I accelerate on my 2006 FX35 (75K). One dealer said it needs replacement (around $800) and said it's not covered by my 100K extended Infiniti warranty(not sure about that)...anybody have any experience with such a thing? Could it be something as simple as a loose bolt, possibly the heat shield?

Thanks!

Most likely needs a muffler. Kind of common on these cars.
