i dont have a O2 bung on my 99 LS exhasut manifold...guessing it was on the cat instead...dont really wanna get another cat..so which exhaust can i use that have a O2 bung already on it? do i have to extend the wires for the O2? i'm using a obd1 integra harness instead of the civic harness...this motor is going into 95 coupe...thanks

 

just have a bung welded on for about $25 at a muffler shop

 

 

 

just put the o2 sensor in your **** bung.

 

LOL...funny but i need some actual info..lol

 

Seriously tho, just do what that other guy recommended. Most weld shops will do it for dirt cheap with great quality.

 

only thing worried about...i would do that...its just that the oem bungs are deep inside the header...as for weld ons they sit on top of the head...just wondering if that would throw off the readings

 

i know i could do that...but what header could i use if i didn't want to do that?

 

info

 

damn no one know wat header to use with a LS that has a O2 bung..very surprising

 

Hey again the wire on the harnees should reeach the cat if the bung is in the front. On the 94-96 LS mani, which is what you want to find if you dont go aftermarket, the bung is located like 2 inch up from where the cat and mani bolt together.

 

as said early, jsut go get a bung welded in, it won't throw off anything...

 

it's nowhere to be found?? did you check the back side of the exhaust manifold? because I was working on d series for a while, and was used to the sensor being on the front, but when i got my LS, it was on the back, before the cat.

 

nope...nothing there
