4-2-1 CTR header vs. 4-2-1 DC Sport header
hi. just wondering if there is any difference between the two. i know the CTR header is a one piece and 4-2-1. what would some of you on this board recommend? the header i have a DC Sport one piece, 4-2-1 header right now. is there any gains if i switch in the CTR header. or is it goin to be the same. also, how to tell if it is really a CTR header? let me know. thanks...

A real CTR header (JDM) should have a 2.5 collector. A USDM Dc header has a 2.25 collector. Do the math
