I just gave it the maglight exam and it looks to have a baffle nearly 11" long that leads to the cat located in the lower belly of the pipe. The baffle looks like it can be extracted by removing the rivets in the outer aluminum muffler ring. It also looks like the baffle is wrapped in some sort of material. The rivets make sense as they're there to facilitate repacking the baffle if it gets old/clogged. This is getting intriguing . . . .
