So I just had the headers installed monday and I already feel a difference. They also sound very good and are not to harsh, if your not on the gas too much you cant even tell you have them. But this morning while driving I noticed my SES light on and I'm preatty sure now i have to get the o2 sensors tuned out. BTW I ordered these headers with cats and all the air fittings so i worder why the light came on. Is just tunning out the rear sensors solve this problem and is this the best way to take care of it?

You've got to find out what the codes are. If it's the rear O2s that are throwing the code, just turn them off, via tuning software, and either just leave the O2 sensors plugged-in your y-pipe (to fool a visual inspection), or get a couple 18mm x 1.5 oil drain plugs and plug the bungs. But the code could because your LTFTs are now outside the threshold for the computer to adjust, or maybe an EGR or AIR malfunction. I think some auto part stores will scan your car for codes for free, but it's impossible to know what course of action to take without knowing what the codes are. Good luck!

Thanks, Ill check out the codes and see whats going on first before I do anything.

Well I just went to a shop here localy and the guy checked the codes and it was the o2 sensors. We had them deleted along with the air pump and my speed limiter wich was at 118. No more SES light
