CEL after headers
After installation of LT headers, x-pipe, mufflers(No CATS) had a problem. The place that did the install placed 02 sensors incorrectly. I had the car taken to a corvette shop, they fixed it easily, but now I have CEL and it is throwing P1153 code. Car performs fine now, no rough idle etc. I looked up the code but it does not specifically tell if it is the rear sensors or front ones. I suspect it is because I run catlees. The light was solid when came on, I cleared it using DIC, has not come back yet.
Next week I 'am getting a real full tune on dyno. I just wanted to make sure that it is nothing to worry about and related to absence of cats.
Thanks
Victor

This is a continuation of multiple threads on this from this poster. Get a CLUE dude and take it to somebody that knows what they are doing. No cats and rear sensors will not work without tuning the rears out, you will get codes. The computer compares the front to the rear to see how well the cats are working, with no cats-I bet you can FIGURE OUT THE REST.

You are not supposed to run rear O2's without cats. Install the plugs and get it tuned for best performance. I have cats, no rear O2's and no codes on my Z06 using LG Streets after my tune.
