rear O2's

I am gonna take my car to livernois to have it tuned. I just did a cam install with all the basic bolt ons. Now I want to know do I have to plug the rear O2's in or can I leave them off the car? thanks Joe

Get rid of them and when you go to get the car tuned just have them tune out the rear O2's so it shuts off the SES light...easiest way to go!

if you didnt upgrade the exhaust, you will still have holes in the pipes, so you might wanna plug those up with something

yeah I have a 3 inch H-pipe so its ok if I dont have the O2's plugged into the harness?

it's ok that you don't, but I would probably plug them in (if you can) just so they dont drag.
