OK, here is my opinion. This flue may work really well to modify a Smoky Mountain cooker, one that doesn't have a flue at all but a vent on top. I really don't think it is worth the effort on my smoker. I really couldn't tell the difference with the flue or with my 6 inch stock flue. If I turn down my gas all the way and there is any wind it is going to blow it out regardless of the height of the flue. I do think that if you didn't have any flue at all and just the vent, this would work great. Just my observation and professional expert (refer to personal statement) I'm sure what I'm talkin about opinion.
