Downpipe Question

Im going to install downpipes on my car but i do not have the BMS DP fix nor do i have a JB4 (Had a JB3 but removed to send for an upgrade to the 4 and never got to it). My question is that i know it will throw a code due to the O2 sensors. But will it effect the performance in anyway? Like LIMP mode or anything like that?

Please Educate me. Not looking to hear horror stories about exploding midpipes or Tree's dieing cause im polluting the environment.

Apologies if this has been discussed already, tried the search and couldn't find the info i was looking for.
