OK, so does anyone know if Tone sells that part seperate or is it something I can fab up out of carbon? I mean we are only talking about a measly 5 psi here. I saw a guy fab up a complete intake manifold out of carbon for a turbocharged subaru H6 he was going to use on a plane. At 5psi + around 14-15psi atmospheric pressure, it seems doable, or does the cast adapter do something or have something in it that is special to it alone?
