Headers are a great mod for the 3.0. LCE are probably the highest quality, but I've also heard good things about the Doug Thorley ceramics. Summit Racing sells them for $577. That may include the crossover and pipe to the cat; I know it used to, but the listing isn't clear, so I guess you'd have to ask.

EDIT: on Thorley's site, the instruction sheet does seem to suggest that the connector pipes are included (but I'd still ask):

So wait... purchasing this http://www.summitracing.com/parts/DTE-505C/ comes with ALL the pipes to connect it to the cat?

Seems kinda silly to say something like that. Not everybody wants to spend ~8+ hours and well over $1000+ for an entire engine swap. I bought my Doug Thorley headers from Summit for $525 shipped. It's no race truck, but it made an improvement and I feel safer knowing that crappy factory crossover is gone.

my truck came with a set of headers, and i have no idea who made them. but it's a 3.0/auto. the throttle cable to the transmission is now burnt from a sloppy install. from the 3.0's i've driven though, i would say headers only made a *slight* difference. i wouldnt buy them for performance alone. the price:performance ratio just isn't there. but to buy them for possible head gasket longevity and peace of mind is another story.

North west off road makes headers for the 3.0. I would google them. I checked them out before I bought mine from Downey. They were to be second best to downey by reviews. but there is such a thing as a cheap mans header which will get rid of your factory y-pipe which is where they say you loose your h.p.
