Other than CEL, car runs fine.

Yeah, the 90 degree extenders wont work on this car. It reduces the amount of exhaust the sensor sees by too much. That is why you just can't leave the sensor hanging outside of the exhaust pipe. The computer has a preset range that the sensor has to read to not pop a CEL.

Did the OBX headers come with the front wire extenders?

Kooks cats work with OBX longtubes. However, if you run the 2" extenders on the rear sensors, you can run the straight pipes that come with the headers without a CEL.

LOL, thats right. I got confused with the front and rear. I had to buy the wires for the front not the rear. Sorry about the confusion. They say that Kooks highflow cats work with OBX. Or, just use the cat deletes that come with the headers. If you dont mind getting a shop to weld, you could pretty much use any highflow cat with the system as long as the size matches your header pipe and Cat back system. You will need 2 extension wires with the OBX headers no matter how you install. No, the headers do not come with the extensions.

Don't know about OBX but generally, long tubes always fault the aft o2 sensors.
