Catless Mid pipe
I'm going to be installing a AR headers and mid pipe with out cats. Im pretty sure its going to throw a check engine light because the rear cat are not going to be there. Is there a way of turning the check engine light off with out having it tuned? I want to wait to get it tuned until i do heads and cam. Any suggestions?

I checked with a tuner with questions about mine and getting rid of the cats. He said that the only way to get the light off is to have it tuned, or disconnect the light itself which I don't want to do.

If you are getting headers you must get a tune or you will never realize the full hp gain they can provide. During that tune you can turn off your rear (post Cat) O2 sensors, thereby eliminating the CEL.
