I had the same problem a few years back.I had a new exhaust installed from the manifolds back and my passenger side pipe would work loose no matter how tight I cranked on it.I finally found out the donut was slowly shifting around due to a missing piece.Pull the pipes down and make sure there is something that will hold the donut in place.My driver side manifold had something to keep it in place but the passenger didn't.
