well they come out of the inners obviously when the outer ones are closed. The valves completely close off the outer tips. And when the valves are open, the exhaust gas comes out of all four, but it's going to look like it mostly comes out of the outer tips because the outer ones are pretty much straight pipes (so the gas will go through the path of least resistance and biggest opening, the outer tips).
also, it was 45 degrees out when I filmed it, so it looks like theres way more exhaust gas than there is.
