O2 Sensor on Cat.

[1NonlyAccord]

Ok so i just got my 4-2-1 Headers in and the O2 sensor is in the proper spot and everything. But the "Hi Flow Catalytic Converter" does not have a spot to insert the O2 Sensor. What should i do? Leave it? the guy that put my exhaust said to get a hi flow so i did, and not to get a "test Pipe" cuz it wouldnt make me run right, itl mess the computer up..

:???:

someone told me to just take mine out of the cat and put a pug in the hole because i converted to obd1 and i did not need it.

if you are still obd2 you will need it just weld in an o2 bung

[EmminoDaGreat]

put an o2 bung behind the cat, and you will be fine.

let me guess ebay shit right.. don't feel bad my little d that could rocks ebay exhaust as well plug it into the last hole on the header

yea i actually got it off ebay..its the OBX racing Hi flow Cat..
but im pretty sure its just a resonater.

I got the obx header and downpipe for my altima and its was great

yea people say OBX is junk, but i have there 10.3mm wires and there hi flow cat and there fine. I have some chrome jdm headers, so well see how those do.going to install them today in class.:goodjob: needed the air rachet to break loose the rusted bolts underneath.:crazy:

i had and obx turbo manifold and it cracked three days after i put it on

i busted three Ebay Headers for my civic.. lil ol' d that could tho... but i only pay like 10 bucks shipped for the a peice so i figured fuck it for that motor

[Extrememustang]

Yea I had the obx 10.3 wires and they fit but didnt go all the way down, kinda long. The header seemed fine but I only had them for a month till i wrecked the car.

ok so i got everything bolted up and the o2sensor on the headers and i left the one what was orignally on the cat. the check engine light is on like i expected..and it sounds ALOT deeper and louder.with a lil sqeel/air sucking from the intake noise..any1 have any ideas?

[§treet_§peed]

intake whistle ftw... like i said plug the second one in the back of the header.... unhook your battery for 30 minutes
