Chevrolet Camaro 1967-2002 - Headers/Ypipe.rear o2sensor???

Im doing pacesetters LTs and Tsp y pipe in my 99SS. What do i do with the after cat o2 sensors?

if they are emissions necessary in your area, weld in some bungs...if not, get someone to tune them out of your computer.

you should tune your car after LTs anyway so just get them tuned out.

they will be fine to run without a tune for awhile? untill I get it tuned right? just tuck them up high somewhere?
