I don't mean to resurrect a 4-year old thread but if the OP is still active here, I would love to hear if he was able to solve the leak?

I just got a bunch of O2 codes pop up on me on my 2017 SS. I have the Kooks headers with the catted connection pipes to the stock exhaust and everything had been running perfect since the install in the early spring. (Also had the car tuned at the same time)

Only thing I can think changed was that we went from 70+F temps to barely 32F temps in about a day and maybe this is causing a connection (or connections to leak).

I should be able to get under the car in a few days once the temps warm up.

It is definitely not the problem of the harness on the passenger side touching the header; I made sure to move that out of the way and heat insulate it at the time of the header install.
