Got this pipe A with my 97 jdm b18c swap.

Is there suppose to be a o2 sensor bung on pipe A, or it only occur on jdm pipe A's?

 

i know the ITR and LS USDM vehicles look like that.

 

heres a picture of a 97 usdm LS pipe A



notice how the two o2 sensors are on the cat.

 

that is the correct location for the primary O2 sensor. (for 98+ R's)
and yah that looks more like a USDM header than a JDM.

 

I don't think the pipe A that came with my swap is a USDM unit. If you look at the above picture, notice how #8 does not have a bung hole for a primary o2 sensor but mine does. The primary o2 sensor is on the cat (#3) so that led me to believe my pipe A is not a USDM unit.

 

I checked a friends car that has a '96 JDM ITR swap and it looks like the one in your pic.

Which also looks a lot like the one I got on my '00 USDM ITR swap.

 

great, thanks for the info.

 

yeah but number 9 DOES have a hole for the O2

 

my OBD1 LS had the hole in the header, not the cat. I used an CompTech ITR header when i did my upgrade.
