Well here is my modified pipe. I added a 2.5" tapered section between the pipe and the header. Wow what a difference that made. It now comes on the pipe at about 10 mph and will pull up some hills at better than 40 when it would fade to 35 before. Top end is in the mid 40s. I didn't get a chance to finish grinding off my welds as I had one of those O-sh!t moments when I ground through the cord. I worked on it for a while with a dremel and my cut off wheel but I really missed not having my slap pad.

I slapped some paint on it. I probably will add a second brace but it works.
