Hello, I am curious what are some opinions on my situation. I have a eg with c5 bottom and gsr head, s2s2 cams, soon to be diy itb, hondata, blah blah blah. I currently have a JDM itr header, would I benefit from switching over to the comptech 4-2-1 and if so what do you think my chances are of finding someone to trade me? I want to break well over 200hp but dont like spending 700$ + on SMSP or others. Info please. Prefer experience.

 

bump cuz i wanna know too. In the process of getting a 4-2-1 comptech header myself.

 

And another ? to boot. Does comptech sell a"jdm" version with a 2.5 outlet?

 

you would be better off keepong you jdm header, or getting the jdm dc4-1, I wouldnt waste your money on the comptech header. Or just sell you current header and buy an An-r
