Installing Jet Hot LTs on a 97 Camaro. What is needed as far as O2s so I dont get the SES light?

The headers do have the 02 spots.

 

you will need 2 12" extensions and 2 Oxygen sensor sims if you're taking out your cats. I reused my O2 sensors and they looked original and no problems yet.

 

You need two 02 extensions, and two o2 sensors. And if you are getting rid of your cats you need two MIL eliminators or you need the rear o2's programmed out of the computer.

 

Don't put your good O2's in for a few miles as the coating on the inside might ruin them.Try to run it with them out(don't leave them out) or get an old set.

 

So would it be better off to put the old ones in, then replace them? Or is there some way of capping the holes whiles braking in coated headers? Ill be starting my install of Hooker super comps next weekend.

Where is the best place to order those 02 extentions?
