This place makes exhaust flanges for DSM cars

I wanted to know if you guys know of any places that make an intake flange for our honda motors, or an exhaust flange?

I want to make a custom ITB setup, and need a flange that i can weld onto, to make some straight pipes to mount the throttle bodies onto. I know I can just cut the runners off of a normal intake manifold, but the runners are never straight. OBX has straight ones, but I don't want to pay 150 to hack off the plenum to have 4 straight pipes welded onto a flange.

Where can I get a flange like this one, for an intake on a D series Honda?
