I've been shopping and I'm not forking out the money on a 1 piece header, to me that's not much of an improvement over a properly ported manifold. If I can't find a good set of decently priced, long tube, two piece headers that I can run dual exhaust with an X pipe with than I'd rather port my manifold and run 2-1/4" single exhaust so I can spend my hard earned money on something else.
