Oxygen sensor problems?

So I put in a Kooks custom exhaust ( 6511 complete-GE ) and ever since ive been getting a insufficient switching bank 1 and 2 sensors 1. Do I need to but a tuner and just have the car tuned or is this being caused by something else? The car has 8k miles on it so I know its not bad O2 sensors...

It is caused by the sensors being moved further away from the manifolds which causes a lower operating temp than is expected. I do not know of anyone finding any permanent solution other than to have the codes for them tuned out (turned off or removed)... Be aware, any tuning will void your powertrain warranty. There is no tuning software that I know of that can defeat the checksum counter in the ECM. Some vendors have stated theirs is undetectable but also don't guarantee it either...

I used sparkplug non-foulers for the rear O2 sensors. Drilled out the middle 1/2" so the o2 sensor fits. No tune and no cel.

I did a lot of research to figure out if there was a solution. Seems with LT's if you move the rear O2 sensor out of the exhaust stream keeps the cel from coming on. Also seems that this works better for those of us in warmer southern climates. In summertime I suppose it's good for everybody. Since I just installed them, everything is OK, I'll see how things go when we get to winter, which down here in NC is nothing like the cold the guys up north get. Most car parts stores sell them in a 2 pk for about $7 give/take, so for around $14 bucks and a little time to drill out the ones that the sensor goes into, it's inexpensive enough to give it a shot.

I doulbed up the non-foulers like this

The decel popping is more pronounced with the LT's, so I might still take Midnight to Heintz Racing for a tune anyway. Maybe for my b-day next month.

I found that without a tune my headers were only worth 5 rwhp. Without a tune your mixture is way off. If you have an automatic a tune will get rid of the AFM and that very annoying drone.

Nancy, I applaud you for your innovation, good work.
I knew that after installing my 6511s complete, eventually I would see a CEL, so I bit the bullet and had Heintz Racing do a custom HP dyno tune. They deleted the AFM and it was worth it just to get rid of that. The tune also included tightening up shift points. They are really good folks to do business with. Zach even call me a week later after th ework was done to find out how the car was doing, now thats what I call service.
