you might not want to use conduit...its galvi and it sucks to weld....+++++rodYes. Your project was not only a work of art but I also suspect a real performer. To be honest though, considering how much work you put into it, and $30 plus, it makes more sense for me to just buy another one from Pablo and Jim.
I can get chinese exhausts for less than a saw buck apiece shipped complete with flange etc.. And conduit is almost free at places like Lowes and Home Depot. Soooo... the gears in my head start turning (or is that a stripping sound I hear? ).
