    Sometimes when I start my truck when the engine is cold there is a sound like a flap closing and it sounds like its coming from the exhaust, metal hitting metal sound. I have hit the muffler and cat converter with a rubber mallet to see if there was a baffle loose but nothing rattled. I have 24 thousand miles on it so it would be kind of odd to have a broken baffle but things happen. I would take it to the dealer but it may go 2 weeks without doing it. Has anyone had this happen? Thanks
