I have one burn tube that has seen better days and needs to be replace soon. I went to the Avalon dealer and was quoted $200 for 2 new tubes. I was looking at them and I don't see why I couldn't replace them in Stainless Steel for a lot less money. Has anyone done this? Any Idea on what I need for pipe, tubing, thickness, type. I don't have a lot of experience with stainless, mostly I stick with steel since I can weld it with my little wire feed lincoln.
