I really don't think any shorty header is worth the effort, they repeatedly show very little gain compared to long tubes.

As far as EGR I don't have to worry about it, my truck was originally a 5.7 truck and they didn't have that crap on em. This thing with the 5.7 top end and cam tows a lot better than any stock 6.4 truck I have ever driven and better MPG.


I am not causing global warming, I am just trying to hold off a impending Ice Age!
