I just noticed, that on BMCRace.com it mentions that the T3 Log Inlet Flange is designed to be used as an insert, and not as a saddle. Does anyone have pictures of how this welds in?

Kind of hard to see in that pic but I'll try to explain it.

The flange is ported to the inside diameter of the pipe. You notch the pipe until the inside of the flange is flush with the inside of the pipe then you weld around and inside. It's just a rectangular notch nothing fancy and it's easy to weld around.


Note: this pic demonstrates how far you can rotate the flange toward the bottom of the manifold. This is MAXED the expletive out.
