header bungs or not
I am putting Melrose LT headers on my 95 coupe vette. Do I need to order headers with O2 bungs in each collector,or can pcmforless reprogram my pcm to not need these 2 o2 sensors..also cats are comming off...Borla exhaust the rest of the way back is already installed Any pros or cons to doing this.[if it can even be done] P.S.L. Fla.

Yes, you need the O2 sensors. You can't eliminate them on your car, so you'll need the headers to have bungs.
When you hear someone talk about eliminating the O2 sensors, they are talking about removing the O2 sensors from behind the catalytic converter. Some cars have 4 O2 sensors, one in front of each cat, and one behind each cat. The 2 in front of the cats are mandatory, while the 2 behind are not. No one actually eliminates all of the O2 sensors from the car, just the secondary ones from behind the cat.
