The P5 exhaust has the wrap you mention.View attachment 8699
Interesting! I didn't know that. I'm still on the fence about that stuff. I've never installed it, or had it installed on any of my vehicles, but "they say" your exhaust will rust out faster since the wrap absorbs moisture after the pipe cools down. I've never seen anything that proves it one way or another.
