ok i got my dc header the other day, and i'm comparing it to my stock manifold, btw its a jdm b18c, its not in the car yet. so anyway, the stock manifold has an o2 sensor behind the oil pan, the header is missing the bung? is it because its the jdm version? is there an o2 bung on my cat? do i need something i don't have? any help would be great, thanks

 

forgot to mention, its a 94 cx if it matters...

 

im not sure but i installed my dc header onto my b16 del sol last night an dthe header had a 02 already drilled...maybe yours is different because its jdm u might have to drill your own.....

 

the header isn't jdm

u said it was JDM?? if its US DC then u better send it back because they come pre done

 

i had the same problem, got my DC 4-2-1 header for my b18c1 and thought it had a bung for the o2 sensor on it, but it didnt so i drilled a hole in the piping thats inbetween the header and the cat (didnt want the o2 sensor on the cat because the heat can ruin it or throw it off) and it worked out, just had to get the bung, drill a hole in the pipe, welded the bung over the hole, screwed the sensor in, and it worked for me

 

mine had one too

 

the motor is jdm, not the header, what do you mean they come pre done?

 

they already have the bung hole drilled........haha bung hole

 

oh and mine is a 4-1 so theres no room for the bung to be drilled

my friend got the 4-1 DC header for type-r and it already had the "bunghole" but when i got mine, it didnt have it...wierd.

 

if your car is a 94 it is obd 1 so it will only need 1 O2 sensor right, I had a dc header on a my usdm b18c1 in a 92 with just one O2 in the cat and I get no CELs, I think that is the way it is on obd-1, someone correct me if I'm wrong....

 

jdm b18c is obd-2.....needs to have 2 o2 sensors

your header came from a b-series obd-1 car car obviously

either drive with the cel, or drill and weld in a bungholio

thats not true....mine is DC stainless 4-1 and it came with it pre drilled! and there was plenty of room

 

my engine is obd 1 its from a 94-95, it only has one 02 but its behind the oil pan right before the cat, i guess i'm just going to have to put a bung after the header, unless anyone else has an idea...

yours has to be different then, because there is not room, there is maybe an inch between where the pipes merge and flange, and that space is occupied by the mounting bracket

 

yeah really different dc 4-1 header..maybe yours is fake? lol i just put it in last night i would know i have one...

 

i know its not fake, but its probably the the same one as yours, its for a gsr, and its a 4-1 ceramic coat. i just don't see why they wouldn't put the 02 bung on it, oh and its also about 5 inches shorter than the stock header, the stocker goes about 6 or 7 inches after the bracket, as i said this one only goes about 1 after they merge and that space is occupied by the bracket, i guess i'll have to make a pipe or something, or i might sell it and get the jdm one...

 

can u post a pic of it?? i dunno its weird it shouldnt be short.....ill search around and see if some dc are like that

 

here

 

try posting it one more time i dont see anything yet...im going to go in the garage jack my car up and take a pic for u ill be back in a few

 

yeah i screwed up the firest time i had to edit it

 

damn that this is short!!!!! ill post my pic withing 5 minutes brb

I have a 4-1 dc sports header and its from a 00 si. I actually got that 02 hole plugged up with a spark plug, because the pr3 ecu looks for 2 02 sensors that are closer to the head. I guess I can always hook up the spark plug and shoot some flames jk.

What car did you order the header for ? That is where the mistake happened.

 

here is mine on my 94 del sol...see the difference? its for a 99-00 SI...i bet u ordered one for the wrong car like he said...mine has a extra tube on it then yours...
