mshred,
Can you go look at them again? Hedman and Cyclone both always stamped the part number at the bottom of the header near the collector. I sold, and used, HP parts for many years.

Do you know if headers from hedman come with the reducer for the ball and socket flange...On summit it says the headers come with these reducers, but the guy hasnt listed them with his add, so just wondering if hedman actually sells them with all the headers or only if specified.
