I got the SCT X3 tuner I know you can turn off your rear O2 sensors. Now I want to eliminate all the cats if possible, but the tuner will not turn off the frount O2's right? The truck is still registered in Nevada(smog), so you all know how that works. Just wondering what you all did exshaust wise ( if you know a good shop or solutions). Thanks! :help:
