Alright well It's been quite some time since I posted on here but I need help now. I searched but nothing really helped my question. So here it goes. I just traded my highly modded 15.1 sec z6 swapped 92 cx hatch. I traded it for a bone stock 97 dx coupe which I am very happy with. I wanted something to start over with. But anyways I got it with it throwin a c.e.l. for the primary 02 sensor. I knew that when I got it but anyways the exhaust manifold has the normal crack right through the middle to the first 02 sensor hole.

Anyways he gave me another stock header and I think it's a z6 but not sure. Anyways I need to know what all stock headers will bolt up because I know the dx exhaust is a little screwy. I'm trying to go the cheapest route I just need to get that c.e.l. off cause my gas mileage is suffering tremendously. So my main question is what stock headers can I replace it with and bolt up to the flanges for the exahust?

And my 2nd question is if that header I have will bolt up what do I do about the second o2 sensor? I seen the D.I.Y. thread about the c.e.l. light from no cat but with that header I only have one o2 bung. Can I drill a second hole for the second o2 sensor then do the non-fouler plug trick or what? I NEED HELP PLEASE!!!

 

This should fit, not sure though.. I have a stock OEM exhaust manifold from a d16y8 with only 6k on the manifold. It's in brand new condition, lmk if you want it

Exhaust Manifold Warranty:
96-99 Civic

On 96-99 Civic CXs, DXs, and LXs, the exhaust
manifold is welded to the catalytic converter and can
be replaced only as a unit. We've gotten several calls
from dealerships asking what the warranty coverage
is, since the two components are not available
separately, and there can be only one coverage for this
combined part. Here’s the coverage:
1998-99 8 years/80,000 miles
1996-97 *14 years/150,000 miles
* See S/B 98-081, Emissions Warranty Extension,
filed under Fuel and Emissions, for details.</TD></TR></TABLE>

my buddy had the same thing with 98 dx coupe what he did was get a yb header-manifold like yours installed and bought a cheap high flow cat with o2 bung and had a muffler shop make the flange for the end of the cat to go to the rest of the exhaust system. it works good for him and it cost him around 150 Canadian for everything.
