I took this header on trade and was told it was a DC Carb legal 4-1 2.25" collector stainless header, I have my doubt's since DC refused to issue CARB tag after I sent them these photos, stating that it is not a DC header. The runner configuration is opposite from what DC manufactures, missing exhaust hanger and missing tag on number 3 runner.

I won't go into many more details, so as to not flame anybody on H-T, but I am the one feeling burned right now.

So my question, what brand header is this? I need to find out, so I know specs.

 

not sure, but i think all DC headers have some ID on them.

that is a decent style of header but is most likely a no name, or something like a Megan header

 

correct dc headers do have id on them . this headers lock like ebay headers but i mite b rung good luck
