I just bought a t1r full exhaust and it came with a test pipe. (i havent put it on yet) but i dont know how id be able to get past the o2 sensor not being in my old cat. will the check engine light go on? will that effect anything else with performance. how would i fix something like this? thanks

 

your car will run better with o2 sensors... u can go to a muffler shop and have them put o2 sensor bungs in the test pipe.. i know u wouldnt want a check engine light

 

Are you OBD2?

You're name says 95acuraintegra, do you have a 1995?
If so then you have an OBD1 Integra which has no rear o2 sensor.
Which means that you'll have no problems.

 

im not too familiar with the different ecu's. i do have a 95 gsr. ill be really thankful if i dont have any sensors to worry about. thanks

 

Be really thankful then, LoL.
You don't have an o2 sensor in your cat.

Is that the answer that you're looking for.

 

ya thanks a lot. thats a relief.......
