will non catted front pipe effect my o2 sensors?
 
I'm going to be installing my Avo cat less front pipe and Perrin over pipe in a couple days And am wondering if the cat less front pipe will cause any problems with the o2 sensors

No, the O2 sensors monitor the Cat in the header and thats it. Frontpipe header is not monitored by ECU.

Both o2 sensors are in the header, so no. 1 precat, 1 post cat. Hence why everyone gets a CEL with a catless header without using a spacer or a proper tune.
