I'm at the point that I need to weld in my patch panel inside the cowl area where the fresh air chiney lives. If a system like the Next Gen is going to be installed, do I need to put the chimney back, or should I just delete it? Its already cut out, just getting ready to install my patch.

where will the next gen system get fresh cabin air?

I thought there was discussion a while back about this, but  can't recall the details.
