You can email Pfab for the FF manifold and ask him to make one with a T4 flange

 

I was going to do the exact same thing when I wanted to switch out my log. The cx racing manifold does not look bad at all. I ended up finding a deal on a used synapse forward facing manifold and just went with that. It may or may not work out but at the end of the day you will feel much better knowing you have peace of mind with a quality manifold. If i bought the cx manifold i know i would be checking for cracks every other week.
