The original C-Type was the same as the OEM curved header on the OS 2050/2060 pipes. Mugen discontinued it because the new MBX6-80 header is only 80mm wide so it tucks the pipe in closer to the engine on the tight, narrow MBX6 buggy (helps keep weight to the center of the chassis as teh MBX6 buggy is heavier on the motor side). All three headers with the JX pipe (JX15001) fit the MBX6 though.

I still have one of the original C-Type (JX14001) headers still in stock. It's probably the last one out there...LOL
