What offroad x pipes are you guys using? Do I need the extender harness for the rear O2's. I'm looking at a bbk anyone running these if so how's the fit. Thanks.
Well, mine got beat up in shipping, but I was able to unbend the flange and massage it back into shape. I did not need an extender harness, but you will need a mil eliminators or turn off the rear 02's in the chip.. the check engine light will come on after the install
