header question

[white eagle]

I see the other post on installing long tube headers and that brought to mind a few q's.
I was also looking at l/t headers for my 04,5.7 f150
the only l/t headers I could find were 1500.00 for the set.
I see the link of parts list these at a fraction of that price other than price is there that big a diff in headers to warrant that much cost difference ?
(I would rather not list the name of the other set)
What kinda gain do I actually get from this type of install?(other than the pleasing rumble)
I tailor wood (16'tandem)and a boat(17' fish and ski) and need all the power I can muster

Dynatechs are probably the most complete and expensive kit on the market.
Pacesetter is another good kit at the fraction of the price.
But pacesetter doesn't come with the high flow cats but instead with resonators.
So.......
If you live in a state the requires cats this will add a couple of hundred to the pacesetter kit price along with some modifications.

What was the name of the ones you found?

he's probably refering to my thread on my header install of the pacesetter l/t headers. alabama has no smog laws so i'm running no cats
