I recently replaced my stock exhaust with a bolt on Rebel Series Stainless Steel Cat-Back Exhaust from aFe. Ever since I replaced it, my check engine and traction control lights came on. I found out the check engine light is on because of the emissions. I figured it might be the O2 sensors because i went through and made sure all the bolts were tight, but I'm not 100% certain so any other ideas are much appreciated.

Also the traction control light came on at the same time and I can't seem to find anything that I might've unplugged or hit. The only place I have looked so far was all along the exhaust. Does anyone have any ideas on what or where I need to look? Is it possible it could be a fuse or something and its just a coincidence that they came on at the same time?

Thanks

It's always worth a try to disconnect the battery for a minute, and see if that resets it.

Search P0420 and P0430 fault codes here. The traction control is disabled with this emissions fault.

So unfortunately unhooking my battery didn't work so I'm on to check the O2 sensors. How do I know which ones to check and what's the difference between them?
