It makes a vaccum how?

partly by rapidly cooling the exhaust, making it denser and drawing a slight vacuum on incoming exhaust to the muffler.........or so they claim :?

Looks like it creates some type of tornado affect...Hmmm, and remember the other product that creates a tornado affect, it did absolutely nothing. But it says it has a lifetime warranty so someone could always return it back.
