That was a great video - all of the other videos were very unclear and had me looking at the wrong thing. After watching, I went out to my garage last night and easily pulled off the hose and, using a few people's suggestions, removed one of the two foam inserts (closest to the engine). It added a nice boost in engine noise, but only when accelerating past 3,000 RPM. Highly recommended if you happen to like the sound tube.
