For the sake of knowledge let's say both before and after MAF. I know for my 4Runner as an example, the MAF is down line from the air box, so the pipe could conceivably be different pre and post MAF. I'm thinking pre-TB so the plenum wouldn't change.
What does acoustical waves do for power/efficiency?

I have an idea for my air box and started researching and saw some people changing pipe size, leaving everything else stock. Made me wonder what size changes can do for power/efficiency.
