i have 98 ex and just bought a dc header but the o2 sensor on the header is down before the cat and my stock e=header is up top whats up is it the wrong header or can i drill a hole in the header and plug up the one at the bottom?bought header from a aquaintance.he said it would fit 92-00 civic

 

You should have 2 o2 sensors. I think if you get a DC header for your year it comes with the 2 bungs, if not take it to a muffler shop.

 

just call dc and get the o2 extension ... or you can wire up one yourself.. just plug it into the header and crimp new wires to it and the run it up to the clip on the engine.

 

Do not drill a new hole, just extend your wires, that's what I had to do and from what I know there is only one o2 on the manifold and your second one is actually on your cat.

 

what kind of wires do i need to get?and what can a muffler shop do?

 

would any wires work and just splice em in?im off all day tomorrow so this will be my project for the day so i just need to know where to get wires and if i was to call dcfor an extension how much would that run me?

Just like he said above.

When I had DC Header on B15B7 I had to purchase a extension wire from Dc Sports.

I used regular wires and made sure my conections were good, unles you got the extra cash just get it from DC, but me being broke at the time I just used regular wires and did one at a time so I didn't get confused which wires go where.

btw you should have a four wire o2.

 

thanks i appreciate the help this forum is great ive visited other forums and there a bunch of jerks that talk **** but here i always get good information.thanks again.

 

how much would an extension run and how bad can i **** it up if i do it myself?

 

if u have 2 02 sensor's u can just cut off the other one and re-wired it to make it longer. That's what i did to mines then put electrical tape around it and your good to go.
