o2 sensors straight exhaust

[mechanic0078]

I bought a 2013 used raptor and it came with straight exhaust all the way to the back. I love the sound. It's the check engine light that I dont like. I was wondering how many o2 sensors does it have.

I would guess 4. 2 on each side pre and post cat or where the cat should of been. Get two Vibrant rear 02 spacers and see if that cures it.

Has it got the cats deleted? If so do you live in a non-emmisions area?

Yeah its straight all the way to the back.

The rear O2 sensors are probably throwing the code, they are there just to check if the cats are functioning properly. You can turn them off in your tune or run eliminators/simulators. The better option is to get a set of high flow cats welded in, it wont change the sound or performance but it will keep it from throwing the codes, you should be able to get the cats and welding work done for under $200 pretty easily, if you can weld or have a buddy it will be cheap.
