Will I need an O2 sensor if I add and x pipe
I have an 07 F150 4.6 with a y pipe. It's stock and I haven't done anything to the truck yet. But I would like to add a MagnaFlow exhaust system. But it has a y pipe. I wanna change it to an X or H. I was wondering if I needed to tune my truck and add another O2 sensor if I did this.
