I'm using the Nismo 2.75" R Tune intakes (top half) and made my own Custom extensions for them also in 2.75" The stillens are 2.5" so mine should theoretically flow better and more air. but I found a weak spot on the Greddy X Pipe, so I am in the process of making a better X Pipe before heading back up to the Dyno.

 

Think you could fab up some pipes so I can put my strut bar back on?

 

Header wrap defeats the purpose. It is designed to retain heat, not repell it. The idea behind header wrap is to keep the heat in the exhaust tubes and not allow it to transfer to the engine bay. A heat deflective wrap would be better for intakes.
