Cadillac CTS-V - O2 bung placement

Where is the best location for O2 bung on the ctsv?
Thanks!

If you mean for a wideband sensor then in front of the cats. I replaced my stock with a wideband. If you want to retain the stock then I would think fairly close to the current location. Check with your wideband vendor as sometimes they want them mounted a certain rotaional direction.

I realize it has to go in front of the cats, I was more wondering if one side of the car is better than the other? I am not putting a wide band in right this minute, but I have an upcoming tuning session so need to install a bung for now, sorry for not being more clear.

Sorry never heard of one side versus the other prefrerred. Mine is on the drivers side and works great for what its worth.

I was always told the driver side is the side you want to tune out of, it will run leaner than the passengers side (unless the LS2 is different, which I doubt)
