o2 sensor and high flow cat question??? 2006 f-150 4x4

I recently ordered 2 Magnaflow high flow catalytic converters and took them to just a little hole in the wall shop to install them but they said they could not do it because my o2 sensors were inside of my cats. if i were to take it to a proper exhaust shop would they be able to punch a hole in the cats for the o2 sensors or will i just not be able to ever have highflow cats?? i know i could rig it but i dont want my o2 sensor sending bad readings 24/7....Any ideas??

im pretty sure you just install the O2 sensors directly after the high flow cats, not actually in the new cats

The O2s need mounted AFTER the hi-flow cats in order to work properly.

agreed, mount after the cats. dont punch anything in the cats. you will have no problems with any codes or readings.
