Does anyone know if it's possible to fit a Thunderheader for a Softtail to a Dresser? Are the pipes different or is it just the brackets and so on? Used Softtail Thunderheaders abound on ebay... I'm not opposed to welding on the pipe if necessary, if the purchase price justifies doing it, but I don't want to reengineer the thing. A tab or a bracket here or there is no big deal, though.
