I have an 18 2500. Spending 2gs for headers makes me sick. I was thinking of trying the Jeep or Durango 6.4 manifolds and fabbing up the EGR tube adapter. These factory manifolds choke these engines down pretty good.
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.
