If by large companies you are implying the likes of Ford, GM, Chevy, Honda, Toyota, etc... Can you show me one that has put ANY performance muffler on their production cars from either Magnaflow or Flowmaster?
I think AERO has a better chance of going for the large truck manufacturers such as Frieghtliner. Those trucks will receive a larger savings from the fuel efficiency increase, and would be more likely to purchase or licence the technology from AERO.
I do not think it will be such a long road to $2M in sales, but I will await the filings just like the other longs.
