I have a 350 and I have a rattle it sounds like it is coming from exhaust it dose it when it is revved and sometimes at idle. It sounds like it is coming heat-riser or a lose bracket but it dose not have a lose bracket. my question is dose the heat-riser have vacuum when it cold or hot. and could it be my problem.
