I'm not sure how thick it is, to be honest. if you read the dimension chart, which lists ID and OD, you get a wall thickness of .065"

To be honest, I forgot about the local angle. I might have a lead on that that I forgot about (guy who owns a local muffler shop hangs out at the mechanic shop that redid the brakes on by truck when I got down here, took 'em a week and a half and I was unemployed, so I was there in the afternoons shootin the #### frequently.)
