anyone who has aftermarket y pipe

[slowteg97]

i installed a doug thorely y pipe in my truck about 2 weeks ago so far its been great, then out of no where i throw that awesome code where the check engine light goes on along with the all the stability lights so i scan it and it read low efficency bank 1 and the same for bank 2. just seems wierd the code would go off now and not before, just wanted to see if anyone else had this issue after the install, i know i know it common for these trucks to do just strange how it all of a sudden happened. i can clear it out btw and it will stay out for a day then come back.

Could it be the O2 sensors?

maybe 1 of the o2's did get alil beat up coming out but then it woulda said there was a problem with the 02 in one of the banks not the cats. thats what i was hoping for to be honest, guess im not that lucky lol. o well its cleared now probably see what happens as the week goes. the funny thing is my last 2 tanks of gas i got 387 and 395 out of the tank which was great.
