I found the following picture of the inside of them. They look to be the standard perforated steel wrapped in fiberglass. I am going to try them out and see what they do. At only $50 a pair shipped to my house, I can afford to write them off it they don't work.

Perforated should work pretty well then at that ID you should be okay.

They didn't. Not sure where that came from. There is a pinned Dyno Sheet thread in the Sub Forum of most of the bike types, and there is also this one: https://www.hdforums.com/forum/dyno-charts-191/

No. The plug on right - The line closest to the tip is your idle timing (lowest it will be) The part of the line closest to the threads is the highest timing it has reached.That's what I see from this angle and may not be what you're seeing. Everything will change when you get baffles in.

I have found this "guide" helpful. However, take it with a grain of salt and will try to include a link to the actual PDF:

I’ve always liked this chart. I have it laminated and hung on the inside of one of my shop cabinet doors
