No spacers on the upstream O2 sensors! Take those off ASAP, I've heard cases of people accidentally putting them on the upstreams and it's causes issues due to things running too rich, aside from the fact that you're only supposed to put them on downstream to turn the CEL's off. Congrats on the entirely brand new exhaust though, I'm hoping to get the Y pipe and Gibson soon to pair with my LTs
