I was thinking the same thing when I looked at them. The primaries are shiny, but the crossover and 2 to 1 collector at the back are different. My guess at first glance was ebay headers that are cut and a new crossover welded in. Have to agree with Matt on this one. Looks like Pacesetter knock offs that have been modded. That seems like a lot of money for them if that's all they are.
