Did you read the piece I linked to earlier?
It creates a step/pressure-change which disturbs the standing-wave so you
don't get an effect that some feel is counterproductive. ...bill

Some of the manifolds I've seen are very thick at the bend, and that
chamfer leaves a hole that is much smaller than it should be, but it
is the best transition you can obtain without much more work. The
chamfer is just the easiest thing they could do in one operation to
clean up the opening. A straight bore on the same axis as the carb
would leave a horrible step and obstruction to flow.
