i may be ordering headers if my manifolds can't be redrilled and tapped. im wanting the hooker full lengths but summit has two different types listed. their the exact same except one had a longer primary tube? what does this affect?
also another side note, will i need an oxygen sensor with a longer wire if i get the full length headers? im trying to get a list of everything i need from the headers back before i go to my exhaust shop.

Say what? Oh.. you're talking about the collecter end aren't you. Yeah.. no big loss if they can't be salvaged.

Tube length affects the header tuning with longer tubes tuning lower. In this case however longer tubes my just cause more headaches connecting the rest of the exhaust to the headers if it puts the collector too close to the trans crossmember, and that's exactly what these cheap longtubes do.

Not usually, there is enough wire in the O2 harness to reach the header collector.. just need to remove some tape and pull out the excess.
I have a buddy that is a master mechanic. He says long tubes are for higher RPM power.
He's half right... longtubes produce best scavenging at both the extreme low and high ends of the powerband while shorties work best at mid rpms.
Longtubes are more work to install on these trucks becuase there are no over-the-counter Y, H, or X pipes for them so you have to fabricate something yourself. There are aftermarket Y pipes that will work with shorties and easily clear all the 4wd components since they use the stock routing, and when paired with a high flow cat and catback system will produce noticable gains over the stock exhaust. Longtubes produce the highest gains for truck applications(most TQ) but shorties and almost as good and still produce gains across the board compared to a stock exhaust.
Conanski are you saying that for these trucks with long tubes we need a crossover to equalize the flow from all the bends to get around the 4wd components?
okay long story short i got long tube hooker headers i have double checked over and over and i know they r right ones that being said suggestion or tip on making them FIT i was thinking a 4-5 inch body lift kit SUGGESTIONS
There is a reason that 3 inch body lifts are the largest they sell, and even they make a truck look bad with the frame hanging down. IMO all body lifts belong in the scrap pile.
