help me out guys. i thought i read about this header that dc have with two bungs already for obd-0 hmmmm but i cant seems to find that thread. if you guys know where to get them or you guys know that thread pls post up.thanks

 

anyone??

 

Nope, never seen DC make a header like that. I do know that Spoon makes a header with the 2 o2 bungs as well as a few other JDM manufacturers.

 

hmmmm i thought i read that somewhere...if i do get one where would i get a bung welded to. and how much would i end up paying..

 

You can get it done at most exhaust shops, prices may vary.

 

doesn't hasport make this???

Ahh yes, I forgot they just came out with one. But I don't think I'll be buying one soon for $400.

 

ok so say i get a dc header and i ask them to weld a second bung where should i ask them to do weld it..

 

i also need to know where....

can anyone post a pic?

 

I had the same delima:

I have a 0bd-0 b16, with a DC header, and 1 bung. I just took the lazy way out and spliced the two sensors together. I had all the normall hesition problems, and running rich.

But, I have unplugged the O2 sensor(s) and, the PROM seems to be pretty accurate. No hesitaion, better gas milage, and no codes yet. I guess it just stays in open (closed? [I always get confused]) loop. But, I will report if a problem occurs.

 

correct me if i am wrong, but dont most DC headers have the o2 bung at the end of the header for a odb1 car were the o2 sensor is right be for the cat. if you have a obd0 stock header then you can take it to most exhaust shops and have them weld 2 bungs in the same location as the stock ones. and then just close the one down by the cat.

 

you want to have 2 bungs welded on your header!!!! One on either the 1 or 3 and the other on the 4 or 2 exhaust tubes. You will have to block off the bung at the collector, it will not work with the JDM B16 ECU's!!!!!

 

go to hasport.com and check out the hybrid headers

 

I did the 4-wire O2 conversion and have no hesitation or richness.
