no back pressure that you would notice. biggest problem is cleaning the stove and the fact that unless its made of SS it burns out in about a month.
making a texture in the heat riser would be fine. Not sure why you want to do so unless you have a real need for it. we where spinning the gases so the heat torus would move down the barrel. its a cool trick but more work than its worth most of the time
