It's from Knight Sports, I think a few other Japanese tuners did something like that. It's similar to the chair cap mod I figured out a zillion years ago, that's actually where I got the idea.
If you can restrict the airflow out of the waste air pump air that comes from the air control valve you can shut up the "moo". Those just get pushed in the hose. They want good money for what is just some aluminum bar stock cut to length with 3 holes drilled in it.

Similar restrictors come with the Autoexe carbon intakes as well.

Yep, it's just to muffle the air pump "moo". You only need it on the outlet/dump side of the air pump system.
I ran a setup like that for a long time, no ill effects. It's the best way to quiet it down with something relatively small, you don't need a big muffler or something. The stock air box has kind of a muffler built in to it for that hose FYI.
