When I was at SEMA, one of the guys had run over to the BAR booth and was told that EPA was going to start nation wide testing in 2010. This would be all of us. I didn't hear it with my own ears, but have no reason to doubt him. We are all in for it no matter what and your right it sucks. My new 6. 7 may be clean but sure sucks on fuel economy. And when you try to free up the exhaust it just derates the engine so you loose power. Comies is right!!!!!
