Anyone ever have a problem where possibly a part has come loose inside the muffler causing a tinny rattle sound?? My pass side flowmaster muffler has that problem, especially noticeable on start up of cold engine. No repair except replacement I'm sure. Anybody went threw this????

Yup..my drivers side 2 chamber is defective. It doesnt rattle but makes a very weird bapping sound. People are always saying I must have my valve adj. wrong, but it made the same exact sound on my old motor with a hyd. cam.
