For $1500 I would love to see a dyno chart of what gains would be actually made. I tried googling a little but didn't come up with much. Also they don't list the wall thickness on the website, prob schedual 40 tube but would be nice to know seeing its easy to see extended high egts. On the plus side tubular manifolds usually give it a cooler sound... At least it does on turbo cars lol I'd be more prone to run cast mani's on the truck just for peace of mind

Anyone know what gains can be expected with upgraded manifolds over stock ? I'm interested in doing this if cost is compensated with gains

I don't think anybody has posted back to back dyno results with JUST doing a manifold swap(other than steed speeds and that was a big ordeal) And I don't think the gains are much personally. I did ported 6.0 manifolds on mine, and that was for the increased flow as well as I think by having the cast elbow there is less of a chance to blow an up pipe. Weither or not I gained any power I don't know, but it was a poor mans upgrade which fits my budget!:D
