Recently I have noticed about 15-30 seconds after I shut off my truck there is a loud metal popping noise. What could this be?

MORE THAN LIKELY THIS IS A DENT IN YOUR MUFFLER OR CATALYTIC CONVERTER---WHEN IT BEGINS TO COOL, IT FLEXES
THE LONG WAIT, PROBABLY RULES OUT, A BACKFIRE
YOU MIGHT QUICKLY STICK YOUR HEAD NEAR THE MUFFLER AND VERIFY MY HYPOTHESIS, NEXT TIME YOU CUT IT OFF
IF YOU FIND THE DENT DOING IT, YOU MIGHT GIVE IT A WHACK ON THE CREASE (FROM THE DENT) WITH A HAMMER, JUST MAKE ANOTHER DENT (A MINOR ONE....BE GENTLE!!!) THIS "DISRUPTION" OF THE ORIGINAL DENT MIGHT STOP THE "POP"
KEEP US INFORMED
HOPE THIS HELPS
