I just purchased a set of Pacesetter headers for my 1987 B2000 (#70-1140) (
http://pacesetterexhaust.com/85-93-mazda-b2000-2200-headers.aspx). I plan on installing with a Weber carb this weekend. The header came with the header, extension and U bolt. I'm not thinking that there will be any welding or fabrication required. Am I wrong in thinking that?
