Perhaps I don't understand your concern then. But a better example is something like the stillen cai. It's box and positioning pretty much choke it out also but I dyno ran it with the hood open to free up any air and with it closed where its in a pretty tight cage. No difference.

The vacuum effect is weird. That's why when you are shop vacuuming something even extremely light you still have to almost touch it to get it to suck up.

I'm not trying to say you had a silly question. I'm just saying that to put it to rest as a question regarding the kits engineering.
