Default CEL with new exhaust whats the fix?

2000 integra gs. So is there a 02 simulator i can make or buy that will cure this. I tried searching around and found a thread on how to make one but seemed a little easier to just buy one.

did you buy a catback, axleback, or what? i had no issues when i put my apexi ws2 catback on. if you didnt connect your o2 sensor correctly into the catalyic converter that could be the problem.

Try resetting the ECU and let it run and get used to the new exhaust. If it still is throwing a code then you may need a new O2 sensor.

Computer was reset and it cleared the code for a little while then came back on. The 02 sensor isnt even that old maybe like 20k miles

Did the new exhaust change the location of the O2 sensor?
