Sanderson DD7 Headers or TTI "step"

I appreciate the replys on the TTI's and had I not seen the Sanderson DD7's the TTI "step" headers would have been a done deal. The one problem I have with the TTI's is, I am told that they will not work with fast ratio steering, (which along with power steering is a future project). Has anyone out there installed or have any experience the Sanderson DD7's and do you have any photos after the install. It looks like the DD7's would not give me any problems with my future plans and the TTI's might.
