Any one run hedman long tubes 1 5/8 primaries and 3 inch collector?

and when they say ball and socket, is it only a 2 bolt design or do people make a 3 bolt design?

The number of bolts isn't important, a ball and seat/socket is just the way the pipes seal up.

These are Hooker 1 3/4 long tubes with 3" inch 3 bolt collectors. Hedman will look the same. They use flat flanges with a gasket. I'll include a shot of a set Hedman collector extentions. They have a slide on flange that matches the header. Thats what yours will look like if you go with the full length Hedmans with 3" collectors.
