Has anyone heard of a ,I think they are called "Flo-Pro" mufflers at NAPA auto parts stores? Someone at work was telling me they were a generic version of a Flowmaster at just under half the cost (45 bux to be exact). They say they are built identical to the Flowmaster :roll: can anyone verify this? Anyone used them? I plan on a dual exast system around the first of the year and I am on a budget, so I am looking for a good bargain on parts.
