alright. i'm currently running a comptech 4-2-1 header and i was pretty satisfied with it at first. the reason i bought it was so i can be carb legal and pass my smog checks (and i did) and stuff. well...in 2 weeks i'm planning to buy the JDM OEM 4-1 header with my next pay check in 2 weeks. i know skafia is running it in his ITR. he told me it was a great header. what i need is more info about them. maybe a dyno plot if possible. i just want some feedback about them thats all. if anyone wants to place dibs on my comptech 4-2-1 SS header let me know also. i know it retailed for 549.99 on a website but i'm looking way lower than that. hahah just make me an offer.

 

hey quan, here's the header test http://www.automotiveperformanceengi...om/header.html

 

oh wow....thanks man

 

hmmm....it says the comptech 4-2-1 has 2 more HP. how accurate is this? i would of thought the JDM 4-1 header would be better than the comptech header. weird....shoot if mines better than i'm keeping it lol
