I just found this! Will take a while to print, but an ICE Header kit it 800+ dollars, so this is awesome for anyone who wants to design headers.
1.750" Exhaust Header Fabrication kit - Snap Kit by XeonDesigns
Same design as my original 1.625 header fabrication kit. Identical snap system. These 1.750 parts will snap onto the 1.625 parts. Each bend block is equivalent to a 22.5deg pc.. So 4 pcs will give you a perfect 90deg bend. Alignment notches are every 22.5deg as well. Basic parts included: 1"...
