ok so my big question is will my car still run right if i put the 02 sensor in the cat converter..

btw. i have a b16...
i was thinking about getting a gsr cat to pass emision then put my test pipe in i am making with my exhuast


but the b16 02 is in the header. and i do not have a 02 bung in my header so i was thinking i could just put it in the converter for the emissions test then also put on in my test pipe...
so will this wrk or do i need to put a 02 bung in my dc sport?

 

The OBD0 B16 run non heated O2 sensors. this means they rely on the hot exhaust to to heat them up so they read correctly. Thats why OBD0 cars usualy ignore the O2 while cold. Im not sure if your O2 sensor will get hot enough in your cat. Im thinking you might run a heated O2. I wouldnt know if the other two wires are just 12V or not or you can try your one wire O2 and hope it works.

 

correct...but you dont need to run it IN the cat. you can go ghetto.....and find a nut that the o2 can twist into...and weld it on the down pipe of the header.....anywhere.....BEFORE the cat...not after.
