I was driving home today with the windows down and heard kind of a rattling sound when I would come to a stop. When I got home I let the truck idle and it sounds like a marble hopping around in my muffler. You can hear it most on the driver side right where the bed starts. I thought maybe it was a header bolt that was loose and rattling around but couldn't see. Anyone know what it may be? My mods are long-tube headers, magna-packs, and CAI.

Sounds like the inside of your cats are coming apart.
check your plugs and do a search under my name. had the same sound and it was the third plug back on the passanger side head.
would the cats go bad after 3 months?, i bought the dynatech long-tube system with cats, and i've only had them on for about 3 months, im gonna check the plugs tomorrow
