Ordered my H+R Springs, also was wandering where to pick up a dummy o2 sensor so i can get the dp with test pipe and no cat? and does any one know of a revo giac apr or any other company to flash the ecu that is located in NC or right near theNC/SC line

 

I used foul arrestors for my rear 02.....stil got a CEL. Hell I even had a CEL with my Hi-flow cat months before the test pipe was put in. I got a Cat under effeciency code. Now I just get a code about the O2 itself. I don't even bother with it anymore. I have a code reader in my car that I check once a week just to make sure things are still OK and no other codes are being thrown.
