I Recently installed a full Turboback exhaust which included Invidia CATTED dp. and Greddy ti-c single side . I drove 45 miles and a service engine light came on .
*I do not have any programmer installed at the current time.

-Is the light caused by the high flow cat?
-Is it okay to drive like this until i get an Accessport or tune?

What is the code it is throwing. Likely a P0420 cat efficiency code which would be due to the high flow cat. But pull the code to be sure

Did your downpipe or cat come with stock o2 sensor locations?

I had the same thing until I read a thread on anti-foulers. That solved my issue.

Some high flow cats will still cause a p0420. Put on an o2 fouler on the second o2 sensor and you'll be set

Where do I get the o2 foulers at?

They are spark plug non foulers that you can get in the help section of nearly any auto parts store

Yes what he said ^

Although sometimes o2 sensors wont fit well on those spark plug foulers and need to get opened up a bit. Also you might need two because two spark plug foulers are the size of one o2 fouler from what I've seen

Make sure you don't have a leak between the downpipe/Testpipe(HFC) section. That will cause a CEL (even if your rear O2 sensor is disabled.)

Same thing happened to me and as soon as my accessport came in and plugged in it disappeared

Or you can just get someone with ecuflash to turn off therear o2 sensor.
