Default Rattling noise from exhaust...

Heads and cam car w/ LT's to 3" ORY to Spintech muffler. Anyways, when i give it about 70% throttle or more, at just about 2500 RPMS i hear this rattling noise out the back (sounds like it's coming from the passenger side only). It's not really a raspy sound, just rattling. The only thing i can think of is that my 3" outlet pipe is bumping up against the fiberglass skirt cutouts for the exhaust pipes. The tips shake pretty good at idle but would that make this noise?

Any ideas would be helpful, it's really annoying

by looking at your idle clip, them exhaust tips do shake alot. they might outa put a little more tension on the exhaust hanger.

Maybe a long shot but check the clamp where the y meets the catback. Mine rattled there.

Check all pipe fittings as well - make sure y to headers, y to i-pipe are tight, if possible get under it and try to move the exhaust by hand to see where it may be loose.
