LG Header 02 Sensors
Hello all,
I did my research before hand but have not come across anyone with this unique situation.
I stalled LG Street headers, catted X pipe, and exhaust on my car a few months ago and am now getting around to tuning it. I used the rear 02 sensors in the front position using the adapters provided by LG. The rear sensors are not in use and I installed the provided bung nuts. Car is running great, no complaints outside of the check engine light for the missing rear 02 sensors.
The shop I'm taking my car to said, specific to Arizona, they are not allowed to simply tune out the rear 02 sensors from the computer. I will need to have the rears installed in order for them to tune the car and to pass emissions.
With that being said, should I go ahead and buy two rear 02 sensors and install them where the bung nuts are? If I remember correctly, I would need an 02 sensor extension as the OEM rear sensors do not reach the bungs in the x-pipe. Or, the other option would be to run the front 02 sensors in the front, and rears in the rear. For that, would I need any extensions for the front sensors?
Any help is appreciated!
Thank you

Must be that shop, because most shops out here are used to removing the cats, deleting and turning off the rear O2s. They might also want you to keep the rear O2s because they will monitor the "health" of the CATs.
However, because you are running CATs (ie: trying to stay "legal"), you need the rear O2s to be fully "legal".

find another shop... they can be programmed to not report an error or turn the ses light on and the readiness monitor will show " ready" status... for inspection purposes technically they are probably required to visibly look for cats but many places won't even check as long as the ses light is not on and it passes the obd emission test... if you want to stick with the same shop and they are THAT particular just screw your original front o2 sensors where you have the plugs and just find someplace to zip tie the plugs so that it looks like they are connected, it would be difficult for someone to see that just by glancing under the car unless it was on a lift

I mean I could essentially pick up two new rear O2 sensors and install them with extensions, but if it's not needed it'll just save me some money.
