a new noise

["Stefan H. Malter" <smalter@umich.edu>]

hi everyone
i am the usually proud/frustrated owner of an 87 5000cstq
last week after completing my latest round of modifications on the brakes
and suspension(brembo xdrilled, bilsteins x 4, and H&R x 4) i began to
hear a metallic rattle from the front right region on cold starts which
gets progressively louder on acceleration and which diminishes after a few
minutes
somebody has mentioned to me that it might be the exhaust manifold
any other input, fixes for this problem, how to replace/repair a manifold,
what parts do i need, how do i verify if this is indeed my problem
am i running any particular risk by driving on it in this condition
thanks for your help

Stefan Malter
