We like to share what we design. This has not been tested yet, but should be shortly. So don't go building it without your own testing.

Great question. I used 1.5" sch. 40 because it matched the factory port size when I smooshed it oval with a press. If you're making a fancy flange with a loft between the oval and round cross section, I'd think about doing it for 1.25" pipe too.

I used 1.5" because that seems to be the common pipe size. My current manifold is built out of 1.25".
I'll see about getting a 1.25" drawn up. 1.25" shedule 40 is pretty small ID though compared to the ports.
Oh now I remember why 1.5". ACE Race doesn't have 321SS in 1.25 schedule 40.
