Agreed, and that's one of the reasons why I bought the stainless works headers because the primary tubes are 1 5/8" and with my stock motor gave a nice boost to low & midrange

They have the thicker, 3/8" flange and are ceramic coated. Also, in the middle, there are coated, thin flange Hedmans. No one has mentioned tube size. All the Hedmans have 1 5/8" primary tubes. All the C4 Hookers have 1 3/4" tubes. The smaller tubes will give a greater boost in low end torque, with no loss, on the top end, with a mild engine.

Good points. Also all the Hedmans i have see are not "tuned" headers.
The Hooker's are equal length tuned headers

No they don't fail, but with the thin flange they warp and cause you to have head issues. Ask me how I know!!
