2nd link is bad
what are you looking for out of it? do you want a direct bolt in style header? are you looking for more bottom end torque? i like the long tubes more but they are more expensive. depends what you want to go with.
i see you have shortys how do u like them. im looking for more bottom end torque. so far i have fixed the Magnum Intake Plenum Repair Kit. 180% stat 1 in to 2 muffler and gutted cat. soon getting a sct tuner.
I have Edelbrock ceramic-coated shorties and like them very much. Mine's a 4x4, and there can be some clearance issues with longtubes, but I've heard of them working too. I'd probably go with shorties, give a little more passing power. My Edelbrocks are a couple years old, and no rusting or staining or anything.
If you're gonna spend time removing manifolds to put any kind of headers on, then why not do it right and put dual pipes already? I think running headers into a y pipe is pointless. My truck has manifolds but at least its got dual pipes..
