Default need help & knowledge please :)

ever since i got my wheels put on there has been this wierd raddling noise underneath my car. It rarely happens while driving but when at a stop especially while in park, the thing raddles like hell!! I took it to like 3 shops and they all pointed out the muffler. I bought the magnaflow muffler and the raddling still is present! It seems to be right under the dash area (underneath of course). Anyone ever experienced this before?
