is repacking an 03' WR450 (stockpipe) necessary? i searched around the forum and some say you tear out the rivets and some say repacking is not necessary. any clues?

No... Take that endcap off the stock WR muffler and you'll see that she be hollow.

A YZ exhaust has rivets that you drill out and yes those have packing that needs to be replaced
