Issue with thickness - Surface or Extrude

Hello again everyone.

I am trying to use Loft extrude from Start 1 to start 2 sketches to create an exhaust Collector.

It works fine and I can do regular loft extrude but when trying to do thin feature, it only works one way.

It puts the thickness on the outside of the loft instead of inside which is what I need.

The thickness I need is 0.0625 thickness on the inside of the loft.

If someone could please inform me what I am doing wrong so I know for the future, would be greatly appreciated.

Thank you in advance!

Try making a solid model first, than with the shell feature "carve" it out.
