how many here DD a teg with no cat and or o2 censor? will a cop ever check down there to see if u have a cat if u get stoped? what happens if u get a ticket for loud exhaust? do they make u go to the ref and they check all ur exhaust?

my friend just bought a 92 teg and has a b16 in it and no o2 censor or cat and the ecu where chipped so it runs fine without them and full 2.5 exhaust pipe from the headers...would it be super hard to put everything to stock? i mean a new cat, o2 censor blabla it has dc 4-2-1 headers.....

 

i would think simply bc your car passed ins/emissions means its ok. then again i dont live in california so idk.

 

Yes, if a cop is suspecious he will check to see if you have a cat. They can also pop your hood and look to see if your o2 is connected.

It would not be hard to put it to stock or at the very least, emissions compliant. If the exhaust pipe is connected directly to the header, then you will need a muffler shop to cut and weld flanges for the cat.

 

and im guessing we need to re chip the ecu right? cuz the old owner of the car said he shipped the ecu so the car would run fine without those stuff...so we need to take it to a muffler shop and put a cat in it, and conect the o2 censor...i think the old owner said something about the nox censor too or something like that...ohh and the car has a check engine light...im guessing because of that right?...the car runs incredibly fine no problems at all and hauls ***...but we want to bring it back to as much stock as posible...

 

I would install the cat and o2 sensor, then see if the check engine light goes away. If the car runs bad or the engine light stays on - either rechip it or better yet, just get another ECU. You can go to the Pick A Part and grab one from a DA or EF.

I dont know what the guy means by "nox sensor", there is no such thing on that car.

 

ok cool...can i change anything in the ecu with the vafc2? cuz the car has one installed...

now another question...is it worth it to put the cat and o2 censor back on? cuz the car is not bard for a jdm b16a...wouldent we get in the same trouble cuz the car has an ilegal swap?

 

where does the o2 censor usually go on a jdm b16a? in the header?

 

There should be a bung for the O2 sensor near to where it mates to the cat.

 

thanks
