hello everyone! first of all i'll say i have read all treads concerning these headers(obx)
i need some pros here please, i am concerned about the possible cel that would come out from ecu and about that o2 bung placement! i had these headers from a friend and they are not installed yet! i'm not planning of getting any gains but i need to know for sure if i can put them on my car and not to worry about throwing a cel to my car of having issues with A/F ratio cause of the bung placement!
so my question is simple, can i install these headers and not have any problems?

 

i only have now in my basement exotic speed r1-t exhaust and mazdaspeed cai!
i'm planning on buying COBB accessport from mazdamaniac.com

 

Installing this should not cause any CEL unless you mess up the O2 sensor. I installed a BB header and even with an exhaust leak I don't have a CEL. You will have to reset the management (tap the brake 20 times till the oil meter sweeps) so the computer can adapt to the increased air flow. My car idled like crap till I did that and then it straightened right back out.

Other than that it is a pin to install and you'll probably have fitment issues with the CAT, like I did. The header will fit nicely, it is just hard to get it in that little area at first. I jacked the engine up a couple notches.

 

I had mines for over a year with no cells or problems at all, i also didnt notice any hp and they are way lighter thank stock

 

what is the factory air tube for? why isnt there on obx headers? can i modify it to install it?

 

can someone tell me what will it cause not to install the air tube on it???

 

Are you talking about the EGR(Exhaust Gas Recirculation) tube?

What factory air tube are you referring tube?

 

ell on my obx headers theres is a place to hooked up a tube of some sort! but its seems that they made the headers so hat whatever would connect to it wouldnt work!

 

/\ Hey welcome
Im from montreal too. I guess they are ok, they say that the car has little bit more down low.
