i have a friend who has a 2dr 04civic EX,and he's willing to swap he's apexi N1 exhaust with my stock exhaust,and i have a 4dr 05civic DX.i was wondering if it will bolt on to my civic if the curvings are the same,i know the dx headers are diffrent,so if that's the case then i myt as well get he's own EX headers together with his exhuast and give my headers and my exhaust.do you know if that's possible?

 

Not 100% sure but they will probably be different as far as curves and stuff because he has the 2dr and you have the 4dr but I'm not sure cause I only have a 4dr. lol

 

it won't fit. read the sticked FAQ. you'll know that the DX/LX have a different setup than a EX

 

its not a direct fit. With some welding at a shop it can work.

 

If he's giving you the header and b-pipe (with the catalytic converter) along with the Apexi, then yes it will fit. You'll just need to modify the length of the wiring to the secondary O2 sensor.
