greddy charge pipe

ok.. i got nothing to now and have my turbo layhing around in my room
so i looked at the pipes, i looked at how the charge pipe connect to that curve (connecting) pipe...
but the size of the charge pipe is bigger than the cuver pipe, is thit normal?????
coz when i see the pipe connecting from the curve pipe to the turbo, it's the same size as the cuver pipe !!
so is this normal??

your charge pipe is always going to be bigger and if im not mistaking, is that the Intake portion because if it is....then the intake goes on the bigger outlet rather than the smallest, thats only difference i see
