102 intake piping

I need thin wall aluminum piping with 4.25 I/D and 2 90 elbows with 4.25 I/D
There is 4.5" tubing with .125" all which would get you 4.25" ID. I don't know about the sharp radius bends you would require though unless there are some cast ones around for the radius you need.
Here is a 4.5'' elbow I found. They told me the I/D was 4.5''
