Well becoming the official muffler of Nascar doesn't come cheap. Now we have the Nascar logo and Rusty Wallace on the Aero boxes and on Speed TV. That 4 mil bought a lot of clout....now lets see them push their weight around. Get the sales people rolling out ! UPS, FedEx, Large Trucking companies.....can save hundreds of thousands of $$$$$$. Fuel bills have to be going through the roof for these types of companies.
