Default header tubes smashed down

A couple of buddies were over the other night and talk got to headers and led to a video where they smashed all the tubes on a SB chev and on the dyno the before and after HP and torque were about the same. Another buddy said it was impossible so I'm putting it on here to see what you people think. Snakeoil or?
