Id flanges for New Turbo

Hey guys, my buddy bought a S475, 75/87/.90 t4 . The compressor housing has been machined out for 2.5. We are trying to order up the correct down pipe, and a flange to go-to the intake. So far we ordered a Vibrant 5" V band flange and clamp, and realized quickly that the compressor flange is not the same. Can someone tell me what this compressor and Exhaust flanges are correctly referred to so we can get the right stuff ordered?

The exhaust is your standard 4 5/8" vband which is found on most if not all small turbine s400's.

Oh alright. They don't make it simple.... So this wouldn't be what they refer to as the 4.625 half marmon?

That's exactly a 4 5/8" and according to the description, a half marmon. .625" = 5/8".
