They have the option to add the Wideband Bung w/ plug to both sides for only $80 - is this an option worth adding to the downpipes because if so seems like $80 well spent.

Haven't seen/read about anyone using a wide band sensor on this board (for their X5M or otherwise). Presumably depends on your plan, but I'd guess you don't need it as long as the pipes fit in all other meaningful ways.
