No can without a custom up pipe. The FULL RACE header is a dual outlet header designed for the split pulse.
Their up pipe is a twinscroll up pipe with the merge near the flange. To modify it, you'd have to place the flange quite high near the merge.
I think they use schedule 10 stainless, which would take forever to drill through too. That 1.5 scroll has been shown to work well though. If you look at the APS unit which has a similar design, the one that cracks, it has been shown to make good low end, mid and high end power over stock--sort of like harnessing the benefit of twinscroll without being a full twinscroll.

 

I found one... Thank you
