I have seen some posts on these headers, and have heard some not very good reviews on them. Are they good quality? Do they give a large increase in power to the 4.7L? Is it worth it? Anyone with these on their 4.7's let me know how they are! Thanks.

 

What exactly does the Headers do anyway? I am not really familliar with them. Maybe somebody will chime in over time.

 

They help with the cooling and heating of exhaust gases in a way to exhale them faster and more efficiently thus producing more power. Does anyone have a pair on their 4.7 who can help me out in my decision making?

 

ive been wondering this for some time. the only person i have seen talk about them with first hand experience is AIR RAM, ive PM'd him a couple times to no avail, so hopefully he will see this and respond

 

lol well then I guess we're in this together... AIR RAM! We need your help!! I have seen a couple others as well, hopefully someone will chime in.
