Probably a clogged cat. Switch the rear O2's from side to side. If the code stays, it's not the O2. If it follows the sensor, then the sensor is your problem.

Well if your planning on doing LT's in the future, your going to have to get another y-pipe anyway, so i think buying one just to replace the stock y is a waste of money. So i say for now just delete the o2s if you want, and then get some LT's and new y all at once.
