Can you buy one header?

I hAVE THE HEADMAN TIGHT TUBES , they make as much or more than manifolds and cheapo headers , only 7 less than TTI on that mopar muscle test above . Had hooker headers on before the headman tight tubes and car goes better with the headman headers . I have the coated ones and underhood temps are no different than any other headers , have yet to burn plug wires and I have about 8000 miles on the headers
Summit used to sell only one header , not sure they still do though .
