To get broken catalytic convertor debris out of a rear muffler you could do one of two things.
Option 1 (The pricier one)
Go to a muffler place and get them to cut it open then weld it back up.
Option 2 (The body builder workout)
Step 1, Remove muffler
Step 2, Push vacuum cleaner hose up the disconnected pipe
Step 3, Shake it, shake it, turn it, shake it, rotate it, lift it, shake it
Step 4, Remove hose
Step 5, Repeat steps 2, 3 and 4 until it rattles no longer
I went for option 2 which resulted in tighter abs and stronger biceps. It was completely worth it however as it makes a good story.
