Pontiac GTO 2004-2006 - One more header question

Ok so just got in my connection pipes from New Era(still waiting on headers*backordered* I knew the gto had 4 o2 sensors but for some reason didnt the the connection pipe would have 02 bungs just figured the headers would....so my question is what should i do with the rear o2 sensors and bungs??? I already bought 2 24" 02 extensions for the front o2 sensors.....should i buy 2 more extensions for the back or can i just leave the bungs empty and do away with the rear sensors or two rear sims? either way you guys suggest will i need 2 more extensions?

yeah im an artard by the way lol

I"d prolly due the simulators in the rear

Most of the time, the rear O2 wires will reach. At least they did on my Kooks mid pipes. You can't leave the bungs empty or you'll have an exhaust leak. It's best to connect the rear O2 sensors and then just tune them out.
