I have a ferocious rattle in mine that began when I installed my downpipes. It only kicks in at certain RPM's, I'd say from like 2500-4000. It sounds like it's coming from somewhere in the back seat but I can't really investigate because I'm always driving when I hear it, lol. I need to find a buddy to drive while I hunt it down.
