I have a Brylon pipe tucked away somewhere with that feature.
I smoked it once to see if Brylon was as bad as everyone says it is.
It is.
The carb feature didn't help at all, but maybe that's because the pipe is so awful.
I don't see these breather ports now-a-days, and if it was useful I have no doubt the big pipe makers would still be doing it.
Kind of a gimmick like Gillette's adjustable razor IMHO.
