The revenue numbers have changed since I purchased stock in AERO two years ago. At that time the company was just starting up but was already developing a small but loyal customer base. As I said before I called dealers all around the country to see what they thought of the muffler before I gave AERO any money. Then I bought a muffler myself and tested it. It's a great muffler and it does what they say it does. If they would work on getting the word it should take off.
