I clear the codes and they come back in roughly 50 miles or so. They didn't come on within the first 150-200 miles after installing the ART Pipes though. I removed both O2 sensors before removing the original converters. The O2 sensors were both removed by hand with a wrench and a slotted O2 socket so they shouldn't be damaged. Now that I think about it I did put them back on but only hand tighten them.. that could be a problem? lol

Definitely best to be hand removed & installed before wrenching on exhaust bolts....Sound's like those specific pipes may be causing the light-pending you have no exhaust or intake leak.
Unsure how close you are to one of those performance shop's listed in Tenn. w/Dyno,
but they can give you a baseline HP/TQ reading & let you know where your AFR is.
Better safe than sorry; Hopefully other's w/same pipes,intake will chime in & give advice,,,as lean condition's will destroy engine's.
