Which Headers

[jeepguy1948]

This question is probably not for the purist’s out there. I am in the process of choosing headers. As far as I know, there are 3 types. Tube (Like From Red’s), cast iron 4 into 1, and the Charlie Yapp/Secrets of speed 2 into 1 cast iron. There may be more that I have forgotten or don’t know about. Who likes what, and why? (Yes, I am using a downdraft intake)
