Headers for'06 ?
Why do all the Ebay Header listings only show 99-04 and up to 05 on Excursions but no Headers for a '06 and up F-250 V-10s? Is it because of the 3 V engine? Will Headers help a 3V V-10 as much as a 2V?

IMO-there's not enough of a gain there to justify dealing with the installation hassles, noise and future leak issues of thinwall tube headers on a truck.

4:10s with a 6speed,my TT before this new 5ver was around 7500lbs and I got 10-11mpg with it,I only checked my milage once so far bringing 5ver home from Toledo (about 250 mi.) and there was about a 30-40mph side wind,so it might do better without all the wind.

Modern 5ers seem to be getting taller and taller... and a bit wider.
Aerodynamics 101:
Theory: Frontal area (pressure drag) is the primary contributor to aerodynamic drag.
Result: 5ers usually result in significantly lower "cruising" mpg than a TT.
