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

IS3Fifty

yeah Im assuming he has a b16

vti444

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.
