Default Pacesetter O2 Question

Ok, just got done installing the LT's. Now I took out 4 O2 sensors but I only have holes for 2. WTF now?

You have to tap into the exhaust behind the cats for the rear 02's if you keep your cats. If not, then just get sims.

I was lead to believe with long tubes your rear o2 sensors will throw a code, no matter if you have a cat or not. I know with my mid-lengths I have now it throws codes most of the time with the stock cats in place.

Your best option is to just pick up some o2 sims from someone on this site, about 50 or 60 bucks plus shipping, or get your PCM tuned and have the rear sensors removed. I suggest the tuning so you can pick up a few extra ponies with the extra tweeks at the same time. I've never had it tuned before but I've heard the lowest start at 150 bucks unless you can find someone near you that can do it for free.
