Headers for 5.4
I am thinking of putting headers on my new truck. What brands should I look at, and what are the real world number gains for mpg, hp, and torque? Will this void my warantee? I posted in the exhaust forum and no responses yet. I have a cat back dual exhaust with no mufflers if that makes any differnce to what I can and can't use. Will it make any affect to the current noise that is coming from my existing system. I really like the way it sounds, but more power for towing would be nice. Let me know what ya all think, thanks, Levi

Rich, thanks for the info. My current set up is cat back duals (I had to pass emissions). After the rear cat it runs through a big 3.5" or 4" pipe instead of a muffler. Then it splits and runs out the rear. Budget? I hate going cheap on mechanical stuff. I want some quality products that will last. I will check out that link, Thanks Levi
