**DEC** · 02-25-2010

I got ssac headers and will install them soon but i was going to run with out a converter and still needed to pass emmissions so i saw Emulator Rear O2 now will this allow me to pass emmissions? and also where does it plug into? any help would be awesome

it plugs into your rear o2 sensor, i dont think it will pass emissions.

it will just get rid of the low eff. cat code.

it will pass emissions.

just take into consideration that o2 emulators die just like o2 sensors do. if you want to cheat the system space the o2 sensor out so it isnt in the exhaust stream as much.

Listen to bio, and save money. I don't know the exact thread pitch on the o2 bung, but they make spark plug no fouler at your locat auto parts store. You just need to get that and install it, not an emulator. Once this is done you will not throw a check engine because your front o2 is sending a certain amount of resistance back to the pcm. When you raise the back o2 it reads less exhaust gases which tricks the computer in believing there is actually a cat there so the o2 has less resistance back to the pcm. Your only problem with emissions is the fact that they use those little mirrors under your car to check if you have a cat installed.

i did the same thing with the emulator and passed. They would not test my car with the engine light on, the emulator worked to keep the engine light off. My only worry after that was to pass the actual testing and i did with a slp high flo cat.
