Attached is a picture of an intake tube for a Ford pickup truck. It got me thinking about what was Ford thinking?!?!!  And from there, how could we use this. The intake air comes in from the left. It travels past a series of deadend offshoots, of different sizes. Then enters the throttle body after the turn at the bottom. 

In designing the mufflers for our rotaries, there are different pitches that are troublesome. Would a design similar to this work for our ear shattering vibs, and let the throaty V-8 sound thru?

Just wondering
