Even with fabricated end tanks, you can do some little things to reduce pressure loss and turbulence.

Where the inlet tube enters the inlet end tank, I put extra weld metal so the inside could be radius-ed to improve flow out of the inlet tube and toward the right side of the IC:

On the IC outlet, I machined a radius-ed bell mouth piece to improve air flow out of the outlet end tank, although this could only be done effectively with the 4.5" core:
