End of summer my old 67 developed a vibration type noise or buzz without any felt vibration.
I had it on our hoist a few times trying to track it down , car running ect.
All hangers are rubber and good, checked for any places exhaust would or could be touching body , springs , tank.
Walking under the car for the heck of it I slapped both flowmaster 40s lol right side has a piece loose inside rattling around.
Mufflers are several years old but no external rust. Thought I would share because tracking down a ( noise ) can be frustrating.
