I'm trying to identify the header and A pipe on my jdm b18c1 OBD I engine.
My A pipe has an O2 sensor bung. Thought 94-97 GSR's had the bung on the cat only.
Is JDM different than USDM?
Maybe the A pipe was just swapped off another model?

 

I can verify that my 94 B18C (us) _only_ has the bung on the cat, and not on the manifold itself.

 

Ok, so there's no way this is a gsr 94-99 usdm spec A pipe. Darn, I already bought a 94-99 gsr random tech hi-flow cat and DC Sports 94-99 gsr SCS exhaust

That narrows it down to either:
* 00-01 gsr usdm spec
* 94-01 ls usdm spec
* something else, jdm spec (probably not)

I guess I'll either have to buy a used 94-99 gsr A pipe or aftermarket header or have this one shorted to fit.
