got 1 on my ek4 at the mo but tempted to go for dc jdm (cermaic) header as titanmotorsport have ace deal on em. will it be definate improvement performance wise ?

dont give a **** what it looks like under the hood

 

keep the EK9 header!

 

talking about an EK4, but talking about an EK9 as your title. i'm confused.

 

yeah Im assuming he has a b16

 

i have ek4 (u.k civic vti which has b16a2 as stock) but have put on header from ek9 (jdm civic type r). the ek9 header has 2 1/2 " collector and larger secondary piping but primaries are same as any other b16a header.

hope that makes sense

 

ohh i see now. i say keep the EK9 header in that case.
