which y-pipe works best

so i been reading and reading and READING but some of the post are maybe 2-4 years old and a few ppl have complains about the DTLH and others going with the URD Y-pipe but i would assume by now DT would got smart enough to made adjustments so i dont have to cut anything. seeing how my truck is a 2012 notice that the DTLH have were u can put the O2 sensors back in same with their y-pipe, would appreciate the feedback if anyone has installed either one with the DTLH and which makes the less rattling noise cause heard that was one of the biggest upsets from the y-pipe from DT

those r the y-pipes im talking about, and if with either one ill need that O2 simulator.

 

I'm interested in both of these as well. From what I read at those links you do not need an O2 sim. The URD pipe also has connections for that.

"The URD Competition Y Pipe does include ports for the rear O2 sensors. It will not cause a check engine light from elimination of the rear catalytic converters. On the 1GR-FE engine the rear O2 sensors are installed between the front and rear catalytic converters and they only monitor the health of the front set of catalytic converters. You will not need a rear O2 simulator to run this competition Y pipe."

I'm interested if I would gain any performance from them being s/c'd. Also, if they improve clearance. The stock pipe hangs low and looks to be the first thing I would destroy underneath. I don't have emissions tests in my state so not too worried about that.
