    Got a question for you guys. I've been noticed the past few days when I accelerate, I hear a 'clatter' as I call it. Just before I pulled into the driveway tonight, it seemed to be louder. Its a Ford F350 with the 5.4. I hear it more from the muffler than anything.

    Probably a broke hanger

    It even makes the sound when I'm sitting still, hit the gas and it clatters..

    an exhaust hanger, sometimes the welds break then the muffler or exhaust pipe rattles against the broke hanger

    Hm, I look into that, it sounds to consistent for it to be something like that.. its not like it makes the noise when I hit bumps, just when I accelerate, even just a tiny bit

    Sounds like the studs in the exhaust manifolds, they rust and break from heat distortion. Mine did it with only 40,000 miles.

    It's quite simple.....











    They circled the problem on the front of your grill!!

    May be an exhaust leak.

    Catalytic converter cages/heat-shields can make a bunch of strange sounds (as they slowly fall apart).

    I think this is what might be the problem. I was going to look at it today, but things are getting busy awfully quick with this weather! I might just have to bring it in tomorrow..

    Thanks for all the tips though!
